Donggook plays a prank on Sian "They are your sisters!" [The Return of Superman/2019.05.05] 

Sian is the coolest guy in South Korea, y'all oppars could never.

"I'll protect you although I'm your little brother". awww Sian 🧡

*I cried while watching this* *Realizing how much my Baby Sian has grown so much 😭😭*

episodes of sian are always fun because of their father 😂

"Be my older sister but i will protect you even im your little brother...you dont have to do anything"- sian Wow....that makes me cry...i wish to have a son like sian when i have my own family...his really a big boy now....i salute you captain lee....your pranks are really amazing👏👏👏👏

Those two little sisters literally remade the scenes of seola and sua life...... Dad and sian saying oh my God and my goodness is the best

YES Finally thank you so much! Lol the babies are good at acting😂 they call donggook daddy hahaha they act really like seola and sua😂😂

How could those girls played their role so good omg still cant believe they called Donggok appa all the time and didnt cranky at all😭💓💓 add them as cast for next ep please they're so adorable want to see them more😘

Sian looked so mature and more handsome when he was protecting the little girls I think appa would never stop pulling prank even though he becomes old and sian become adult ......😂😂😂

Yeji's "Annyeonghaseyo" and Reaction when she spilled the snacks is so Cute 😍😍

I love how Donggook Appa always think of how to fool Sian . HAHAHA So clever ! 😍

Yeji and Yena is so Pretty *UwU* I would love to see them here in TROS more often , I wish they'll join .....

*I love how Sian doesn't fight back when Yena and Yeji put lipstick on him 😍😍* He doesn't like it but still doesn't do anything because he thinks it's really her Noonas and that they've gotten younger

_Little Sua runs to the Stranger after seeing the Chocolate_ 😂😂 *SO ALIKE , JUST SO ALIKE*

I love how Sian grew up. He enjoys his life yet knew responsibilities well. Whether he is the youngest or an older brother, his love overflows for them. Their parenting is sooo good.

;You're a bad guy! : It's her Dad, though 😂 LMAOOOO

Those little girls were perfect, especially imitating Sian’s protection stance!

WHEN WILL DONGGOOK APPA RUN OUT OF IDEAS!?!??? LMAOOO URI DAEBAK-IE IS NOW AN OPPA. 귀여워요 💖

Oppa Sian😍😍Daebak!!!! You're so sweet, my love .14:25-15:07 . "I'll protect you although I'm your little brother" I miss you and Seungjae. Don't grow so fast 😅

Hahahaha I remember the rice puff road Seola paved when Sian is still 1 year old(?)

I have waited for this, its been a while since the last one. Sian always makes my heart melt with his innocence at a same time being cautious with dad's prank. He knew donggook will always play a trick on him. Such a good, gullible sian. His been wiser now growing up.

_Why is Yeji so alike with Sua_ 😅😂😂 *Somebody explain me this WitchCraft*

14:48 oh my goshhh!! When Seola starts her moves 😂😂😂

donggook is raising them so well omg

*Sian loves Chocolate but still didn't accept it from a Stranger 😯* *My Baby has grown up so much 😭😭*

Donggook appa has a very good sense of parenting...he always involves dem in interacting with each other ..Sian is such a sweetheart 💓..this for sure is a very loving family..saranghae Lee family❣️💗💖

Sian would be a good big brother💓💓He is so caring of them

"I'll protect you even I'm your little brother" 😍😭😭😭

As you can see Sian is gonna be a brave man who will protect his siblings Awwwhh😍😍

Awwww Sian protecting the girls melted my heart! Then he casually told Donggook about what he did. He was so brave, I never seen him so aggressive before. He’s grown up so much.

7:05 "OH MY GOODNESS" omg i love his pronounciation :(

Sian is hands down the best brother. So sweet. I love his relationship with his noonas. 💛

Sian fighting the big man was so funny XD cute at the same time

7:02 I think this is how Donggook would have reacted to the popped rice incident on the inside. Also, that has to be the cutest "Oh my goodness" I have ever heard

*_I TEAR UP A LIL EVERY TIME SIAN SAYS NO TO THE "BAD GUY" LIKE OMG OUR LITTLE CRYBABY IS GROWING UP SO WELL I AM SO PROUD_*

When the babies eventually started saying "no" along with Sian was too cute.😭

Feeling : I wish I was born in Korea married there and had a daughter seriously I would have searched everywhere for Sian to marry my daughter with him 😆😆😆😆

His dad really molded him to a hyung like persona tho he's the youngest. Sian's appa did a great job wooow

I remember when he is still on a stroller and now😭😭😭😭 I really hope he becomes a big brother to twin sisters

Sian is growing up as a young responsible man. Wow! Parents are doing a great job. I'm always amaze at Sian. Such a good boy.

Seola dancing at 14:48 tho. She's really so cute and sassy!! 😍😍😍❤

Plot: Imagine a grown up Sian being protective like this with Naeun when she’s being bullied at school. LOL I can already see it!!!

the twins are so cute and good in acting !! Sian is becoming mature also , i love how Donggook teach his children > v

Aaaaaaah my heart melted when Sian protected the twins from the stranger. 😭💛

Sian has matured a lot💕💓

Oh my God! Sian grow up so well >< i love his last word, "i'll protect you although i'm your little brother" ♡♡

this is the best thing ever! sian is so matured and being the coolest guy ever. Yeji and Yena are so cute they're really act their role very well,they're so cute. I love how daddy dongwook pulled a prank on sian,it's always funny

Wow Sian has grown so much older now 😭💙he’s so smart and kind, and growing up to be very handsome. He would be a good older brother

they shouldve showed the same incident with the real seola a couple of years ago hahaha. they both spilled the rice thingies. soo fun and soo cute :p

Omg sian he such a sweet brother to his sister. Theyr very lucky to have him as son or as a brother. His parents must be proud. Ow i'm melting

Sian,being a big brother is never easy, i really wish i was born a younger sister instead of a big sister,being a big sis/bro means you take all the responsibilities,even if you are right,if your younger sister says that you are wrong,you are wrong lol😂🤣

One thing that i realized when I watch it is, how great dongguk and his wife teach their children to be so responsible and reliable even since they're very young. I respect them very much because parenting is not easy. 👏👏👏

I think I've seen this kind of episode before when Sian is still a baby

AWW this episode was heart touching. Donggook must proud now because all his children are amazing they r really strong to fight any situation. dongook is great dad , bez of him they are strong.

It's so cute seeing how much Sian grew up and How his talking really improved in the last 2 years

Sian said "stay as my older sister but I'll protect you although I'm your little brother" he's so grown up now and so matured 😍😍😍 I love you daebak!!!

Sian is so cute I wanna hug him.❤

I love how Dongkook made sure Seola and Sua came in matching clothes as the younger girls

Woww... I m amazed at those cute little girls... they neither cried nor ruined donggook's plan 🤩😍😇

It's cute how the girls really call Donggook as appa.. 😂😂 n Sian is so brave.. How charming he is when he tried to protect his little sisters.. He would grow up into a very fine man.. 😊😊

Dongguk raised him well :') i love how he's sucha responsible brother

_Sian really loves his Noonas_ 😍😍

Sian and his father have the best bonding 💞💞

I missed you Siannie!! And Donggook appa did a great job in letting him experience how to be an older brother. Sian looks so cool protecting his sisters 💖

Omo!! Sian’s smirk at 2:22 😂

Sian 💗💗. He's a brave boy ❤. And specially smart boy.

Gosh im so impressed about Sian! Aww 🥰 He’s growing up so well. But we also need to give credit to his parents on how they’re guiding him to be this kind of person. Sian has always been kind and calm and loving but seeing this makes me love him even more 😭❤️

Omg i fell for him when he said i’ll protect you although i’m your little brother. Awwww 😍

When he protected them it was so cute I want a sian as well 😭😭❤️❤️
