She showed a performance that filled the stage alone! TWICE - TT & KNOCK KNOCK cover! 

Using a choreography in front of the original cast is a boss move, and she delivered. Loved the chants. Jihyo's remark reminds me how small is the amount of trainees that succeed.

she's so brave for doing it in front of the actual people whose song it belongs to omg my anxiety could never even if I was the most talented dancer lol

How has she not debuted? She is really good. Her stage presence is great.

i miss the loud fanchants every twice performance 😢

not everyone likes songs with cute concepts, but this one I respect because she seems to love and enjoy her performance and perform it with enthusiasm, I'm sure if she's made his idol debut later, she'll be the one best stage presence

She did soo well especially performing by herself

Her stage presence is another level. Let her start now !!! And watching Jihyo telling her this 4:12.... BY JIHYO herself... omg, I know that she can totally understand what this girl feeling right now

most people dancing to cute concept songs must be shy including me but only 80% but i love the way she dances with cute vibes without shyness she's brave totally 1001% !!

she should debut now

Twice 2015-2017 era was my favourite ❤

I'm proud of Twice fanboys!

Wow, she was really good. She really Embodied all the characteristics of what koreans really like in idols. The Aegyo that matches the song but also that one part with the added "sexiness". You could add her into a group now honestly. She really did take up the whole stage. It was a great performance.

she got ONCE cheer as well

Jeongyeon is so beautiful 🥺🧡

Wow, she did a good job

the audience cheers are so satisfying to listen to 😭

Wahhh... To others, Jihyo's comment might sounds irrelevant and unnecessary, just like recognizing old neighbor from your hometown... But that comment is actually powerful as judge and just deserves to be highlighted... Specially as a kpop trainee...judge is recognizing dream of someone and encouraging it to continue her journey. That though they trained at the same time but had huge different now, it doesnt mean contestant was forgotten and not recognized her hardwork before and now. ❤❤❤

Waaaahh Jeongyeon so beautiful 😍😍

She is really good....btw i miss loud fanchants💜

Jeongyeon so gorgeous

Cameraman is Jeongyeon biased

Jeongyeon is so beautiful

OMG that girl came out with a huge performance. I would almost say she could be a stand in when they have an important thing to do. she nailed this performance. I would love to see her again.

I see her as a center in a group or a soloist

crazy how she resembles Sana at times and then Tzuyu at some angles and even younger Momo!

Great cover

Dammit I was jamming and didn't expect to be tearful in the end

her dance and sp is so good.

At 6:12 that talk talk with the hand gestures reminds me of “Talk That Talk” pretty neat to see that it was in old choreo before too.

Best cover Knock knock remember first time I love twice

SHE DID SO WELL

Someone sign her please she is so good

I have so much love for these covers omg

The confidence this lady is on the highest level!😅

The best KPop world in 2018-2019 always remember😭

Omg...i love her smtt i hope she would debut in hybe or jyp or yg ik that hybe and yg is def look for this girl my fav kpop fan or a person who wants to debut yet! Cant wait❤❤

She is so adorably amazing!

She really enjoyed her performance

掛け声が完璧すぎて最高笑笑 ソロでグループのカバーステージは絶対大変なのに全力でやりきってるのもすごいし、twiceちゃんたちのコメントもめっちゃ良いし素敵だな😢

She looks a lot like Joy. Her dancing is so animated and fun to watch!

She would do amazing in a group but the way she carried that all herself I just😭

This is iconic!

Twice's choreographies are really harder than other groups

She is really good

So pretty and lovely girl😭💘 i fall in love with her

She did a great job and twice were proud of her:)

Good Job!! Great Performance!!!

the stage presences …😮

She used to train at a company near jype for 3 yrs

すごくかわいいし、とても華がある。表情がいい。あとは生歌はどうなんだろ？デビュー当時のアイドルってこんなキラキラしてるんだって思いました。

fofooooo, amei o carisma dela

Uau, tão talentosa, espero que ela só tenha sucesso em sua vida❤

Nice job, ONCEs.

those men shouting for their lives had me dying xD

2:47 Nayeon said it perfectly. It was like she filled up the stage with her performance. I could only say she filled the stage with her emotion and abilities. Hope she debuts somewhere.

น่ารักจังง

team thailand ❤

The judges were so sweet

pls jeongyeon looks so ethernal here T_T

I Always love the Thailand Kpop idol bc I'm thai! If she's thai too then I will Always cheers for her

I never noticed how Nayeon's voice doesn't match her face. Like you would think that she would have a high pitched like "kawaii" voice, but it's very mature, which is right for her age. It's just surprising to come out of such a young looking face. 😅

Asome🎉dance

This is so iconic 😭😭😭

Queens

Que más placentero es ver el o los artistas como cantan o bailan su música.

I love Jihyo 🥰😍😘

K-once has to support Twice in their recordings 😢

Savage❤ Knock knock always me 😭

God bless You and World 🌅🥺❤️

Admiro lo perfecta que es Sana ❤️

Que lindo me va a hacer llorar la niña
