Performer Reacts to Seventeen 'Mansae' MV + Dance Practice 

Dokyeom: doing the highnotes in the dance practice Jeff: oh the Seungkwan highnotes

Even when they were rookies, SEVENTEEN were known as KINGS OF SYNCHRONIZATION👑😌

The reason why Seventeen rose to popularity in their 2015 debut was their uniqueness. Out of the boy groups who debuted with dark songs, Seventeen stood out by performing “Adore U”, their debut song, a lively energetic music which caught the attention of kfans. They were also noticed because they were the only boy group in 2015 who self produces their music and choreographs their songs which was a BIG RISK at that time. Seventeen were already synchronized during their pre-debut days because they trained themselves to be that kind of group to prove that big numbers isn’t a disadvantage, which was really frowned upon during that time ❤️ PS. Mansae is their first comeback song!

Everyone else : synchronised Seventeen : SyNChroNiSeD

Girl: *slaps Vernon* Jeff: HOW DARE SHEEEE Same Jeff, same

they were synchronized right from the very start (debut song: adore u)

Fun fact. Rookie SVT added changes in the choreo for Mansae for every music show they went to during the promotion period to catch the attention of audience and give them something to "look forward to". Their debut songs are Shining Diamond and Adore U, though only Adore U was used for promotion. Mansae was their first comeback. SHORT STORY TIME!! Seventeen's synchronisation didn't start from debut. It started *WAY BEFORE THEY EVEN DEBUTED.* Try watching some of their predebut videos. Woozi and Hoshi were scary as rookies/trainees, they both lead most of choreos and dance practices during theit predebut. Hoshi once told another trainee, "because of someone like you, our team will fail" They are both known to be very strict with precision and synchronisation from the moment they started training and some trainees were even scared of them. Seventeen's predebut/training was broadcasted live from 2012-2015 *SEVENTEEN MONSTER ROOKIES* 💖💎

I think they were synchronized since debut but they improved more and more through the years and became sYnChRoNiZeD

Yaaaaaaaaas Mansea is not their debut song, they debuted with adore u And the high notes was Dk's in the end

You know how kpop groups have that one choreo where the main vocal is standing and hitting the high notes on the side while everyone is dancing. That's DK's high notes on the last part. You can see him standing there hitting the high notes on the side while everyone is dancing. 🤣🤣

ADORE U is their debut song, then this is their comeback song after that :))

theatrical kids of kpop was spot on. it’s almost at muscical level

I think they've been synchronized since always! It's just that, the essence of their choreos has evolved through out the years and gradually the movements they started using made their synchronization to pop off. Also, many people know them for their more mature concepts, but originally they started with quite bright discography. It's amazing how beautifully they've shaped their sound so far, along with their experience.

I would've guessed you'd have seen this one already but I'm so glad I get to watch the reaction instead! 😆

the way i GASPED when you finally uploaded this reaction!! lol i'm the annoying carat that comments under every seventeen video for you to check out Mansae, my dreams are finally complete!!!

They're SYNCHRONIZE since before debut, You remember shining diamond? Even in the predebut show they danced always in Sync, yeah captical S.

seventeen is from pledis entertainment, this company is known for being very hard on trainees and a lot of trainees actually cannot endure the trainings and left gradually. plus, if you look back at the predebut clips (seventeen tv), woozi and hoshi did not allow any kind of jokes or playing around when they were leading practices, they also pointed out any kind of mistakes and told that member to do it again and again until they get it correct. this is also the reason why they are so good in every aspect even when they just debuted. years of hardwork, talent and passion 👏👍

Alternate title: Seventeen being synchronized since inside their womb.

In the earlier eras of Seventeen, Jeonghan has his iconic long hair. He looked BEAUTIFUL. Well, until now but yeah

Even during their trainee days they were synchronized.

Mansae is their first cb song, their debut song is adore u

Mansae is the title track for their second album, Boys Be. Released 4 months after their debut.(age range:17-20) - Took #1 at US World Billboard Chart - Highest Selling Rookie Album of 2015 - Making Seventeen the only kpop group on Billboard's "21 under 21 2015: Music's Hottest Young Stars" list Yeah power rookie indeed.

Seventeen has always been Synchronized and Yes Mr DK was doing those high notes

I absolutely love this song and it’s choreography. I always wonder how it would look 2x though😆 like “MANSAE MANSAE MANSAE MANSAE MANSAE MANSAE” per second?🤣

Mansae is not their debut, is their first comeback, they debuted with adore u (and they have shining diamond their pre-debut song)

They've been synchronised from pre-debut. Since they're from company their synchronicity was something that made them quite popular from pre-debut to now, and of course they've only just improved as the years went by

Their debut song was actually Adore U released in May 2015, while Mansae was released the same year in September. Seventeen have been known for their synchronization from even before debut when they did their show “Seventeen Project.” Btw, the high notes at the end is DK. Thank you for supporting Seventeen ☺️

Even when pre-debut, they're insanely synchronized. Especially Shining diamond promotion period, you can see what we're talking about 🥺 thankyou for adoring and admiring our Seventeen 💗

about the ages (in 2015): S.Coups, Jeonghan, Joshua (95liners): 20 yo - 21 yo korea age Jun, Hoshi, Wonwoo, Woozi (96liners): 19 yo - 20 yo korea age Mingyu, DK and The8 (97liners): 18 yo - 19 yo korean age Vernon and Seungkwan (98liners): 17 yo - 18 yo Korean age Dino (99liner): 16 yo - 17 yo korean age (I calculated the ages just by year)

Many are using Seventeen's music as their audition material, as it shows energy youth and complexity of movements. SVT is aware of this and sometimes they even know that someones said these choreos looks easy but not at all in actual execution. That's why they made HengGarae, to cheer for youth and their dreams. What's great about Seventeen music is... it's them, it's about them, it's about their journey, it's their colors, it's their brand.

There is a 2020 version of this as well, they performed it at Mnet

You randomly reacting to one of my favorite Seventeen mvs am I dreaming 😆

their debut was adore u ugh its so good. manse was there cb after their debut. and yes jeonghan was known for his long hair debut days. omg you didn't know wow lmao

Thank youuu so muchh for reacting this mv!!!! I've been waiting for this reaction for so long

jeonghan's long hair was iconic, i miss it haha

Seventeen's Debut song is Adore U. You can tell by the quality of the MV (Their company was bankrupt when they debuted). Mansae was their 2nd comeback song and Pretty U was their 3rd (Pretty U was their first ever Music Show win too). Also all of the adlibs were all DK, especially the ones where you though it was Seungkwan.

*me:* i'm actually not a carat, i just support them casually *but also me* : they were born great, they raise their own bar everytime and refuse to deliver anything below excellence, they are so compact balanced well-rounded sturdy multidimensional i'd dare say the whole entirety of seventeen are beyond the concept of time, they dont live in a dimension we all share they invite us into their self-constructed world where time obeys them and they make of it as they see fit and we can only balk at witnessing the phenomenae of divinity 😛 confirmed Art tm

I always miss your SVT reactions. And finallyyyy, I was so excited to get off from work when I saw your Mansae reaction coz it's been a while since you reacted to our boys. Anyhow, thank you so much for your great analysis and on-point commentaries on SVT's dance. You made my day, Jeff. Thank you so much, til next time. 💗

Yaaaay!! Thanks for doin this Jeff!! 💗💗

I WAS WAITING FOR THIS OMG ILY JEFF

Jeff: How dare she? That's how every carats feel while watching the Mansae MV HAHAHA

I still play this on rotation daily! It is timeless for sure!

Their debut song is called ‘adore u’ and you should also check it out!! To answer your question, they were always synchronised ever since😭 hoshi and woozi was very strict in dancing when they were training, i think that’s why they’re this synchronised

When he paused and talked about volleyball, woozi then looked straight outta Haikyuu

So pleasant to hear more experienced dancer appreciate the difficulty of their choreo. And the beauty ❤

I'm SO happy that finally you reacted to this ✨✨✨✨✨✨💎💎💎💎

SEVENTEEN YESSSS mansae is amazing (they look so young)

I really love the way you react and analyze the choreo. You and Elliot is my favorite.

Jeff!! I really miss your reaction with seventeen. Glad to see this again😍

2015 was the best kpop year for music releases

This is the best react to dance practice of Mansae!!! Thanks for that ❤️💎

they were already soo synchronized before their debut you should watch shining diamond pre debut version!! they also performed mansae again last year and addition to that mansae also means "put your hands up" thats why they raised their arms

even before debut they did showcases and trained like super hard (at the time they streamed some of their practice and I was sort of a casual fan so I remember some clips that are no longer available, but more and more clips are being uploaded to RU-vid hehe). so I think they were able to debut with the *final* product.

Basta si Kuya jeff talaga Yung nag react the best talaga!! We miss Seventeen content so much.

finally, I was waiting for you to react to this. YEY!

Seventeen is very✨ synchronize✨ btw the one doing high note is DK

they debuted with adore u (which is also VERY AMAZING), mansae was their fisrt comeback ;)

i really love your reactions jeff😘

The reaction vid we dont know that we needed 🥺

in the live stages of mansae, minghao actually backflips during his part!! im guessing the room wasnt spacious enough and thats why they didnt include it in the practice

Finally! Another svt reaction I've been waiting for 🥺💖💎

Finally ! I request this for a long time

Mansae is not their debut song however it was their first ever comeback after their debut + svt were known from pre-debut for their great teamwork and synchronisation!! Thank you for your reaction again an amazing one!

Since pre-debut (Shinning Diamond) they were synchronized and then Adore U came like woah this group is in sync as hell

When they are students, their dance steps are very neat. There is a training schedule for Pledis trainees on the Internet, and the training items on the schedule are very strict. After reading, you will know why they dance so neatly.

You NEED to see their most recent live stage of this!!! The contrast will make you cry.

When I learned that they plan their choreography for how it looks like on top too so people up in the high seats have something cool to look at wow I was amazed and I really wish I could see their concert.

this was their second comeback their debut song was adore you and they were king of synchronization even back in 2015 when they debuted! they have such great energy and chemistry as a team, the flawless discography and their personalities and beauty is just a plus, they a whole package of talent

Jeff thank u!! We have few content these days so I love this and yes I watched you journey in patreon where u realized Manse is Seventeen bcoz of the high notes.. the highnote in the end is DK's though..

Their songs are really TIMELESS like wine.

they recently performed mansae again when they promoted left & right 🥺 seeing them perform it again when they're all older just hit DIFFERENT ✨

FINALLY JEFF!! FINALLY!!!!

Waaaa my moodbooster in this morning is see your react to seventeen🥰

Thank you for another SEVENTEEN reactions. I miss it! We miss it! And yes, their songs never age! It will always be a bop. 💖✨

SEVENTEEN were called Kings of Synchronization for a reason! I’m amazed every single time.

the svt drought got me going crazy so thanks for this it was so cute to watch again :)

They’ve always been SUPER synchronised even since before debut! The song ‘shining diamond’ was from before debut and I’m sure there’s a video out there of them performing it live but there’s also ‘adore U’ which is their debut song and it has a mv + choreography video I TOTALLY recommend:)))

Yes! Thanks Jeff👍

Yesss!!!!++ another seventeen content from Jeff!

Seventeen has been sychronized since their debut and still synchronized until now and in the future performances. KINGS OF SYNCHRONIZATION STAN SEVENTEEN STAN TALENT

The chorus is so fun and energetic, perfect for the song

It's easily still my favourite song from them

Seventeen is the most synchronized group even before their debut! Im so lucky to stand them since Project 17! You should watched them from the debut video, Jeff! See how they grow and glow up and more and more synchronized movement they gave!

Mansae was the first seventeen Song I heard and that was i think during produce 101 and after watching mv I fell in love with This song, specially their dance.

as a five-year-old carat, i can tell you that svt debuted ready, talented, and hard working being synchronized and releasing top tier music !! people just didn't know them back then, and didn't bother to, bc they were too many, or that they didn't come from a known company. sucks to be them though, bc they missed out on sht.

THE KING OF SYNCHRONIZATION

YESSSSSSS Seventeen is back in the channel!!!!!!!

Mansae was what got me into SVT and it’s still my favorite song to this day ❤️

this was actually their first comeback, adore u was their debut and they're around 16-20 here in international age so yes, still young and babies T-T

Seventeen is synchronized even before their debut ♥️ By the way, I love your reaction video♥️

Yes. When they debuted they were already movibg as one and creating music and choreo left and right

Adore you is their debut song I definitely recommend it

Thank you for always reaction Seventeen

There's a few changes in jeff's reaction and i am loving it.

SYNCHRONIZED KINGS SINCE DEBUT! This is actually their second song after debut! Check out Adore U that's their debut song and its bomb

we really have the exact same opinions about seventeen! they has always been this perfect for syncrognized (i literally said that yesterday rewatching their first debut stage adore u), I also like to identify them as the musical kids of kpop thats why i love them so much, and they has always put soo much research in their choreos. I think its the first time I'm hearing someone saying exactly what i've been thinking about seventeen for a long time!

I think you should also check out their 2020 live performance version of this song 😭 seeing them grown up and performing this song last year was very nostalgic

They were syncronized during their debut until now. Their moves and dances were cleaned morw after their debut. But back then their moves was already clean but it is cleaner now hhshshshs (I don't know how to explain my point hshshssh) But finallyyyy again! A Seventeen reaction~~ I love your reactions jeff, thank you for this!💖💎

jeff: how old are they here? S.coups: Seventeennnnnn

you should definitely watch their debut song adore u dance practice. their debut keeps on getting moved so they really spent a long time training, that's why they perform so well.
