I added English Subtitle in CC although it's not well-done. Thanks for @dodo617 for Engtrans. Every mistakes you can send me under this comment. I will fix later. Thanks for watching!

i love how proud she is😭

Sejeong's facial expressions XD

Lol when she screamed no when somi sat on the guy's table literally doesn't want the maknae to grow up xD

She was obviously so shock and happy but at her rap part she seems to be so proud that I thought she was being emotional how far she has come and got to do what she love…

She's so proud of her little sister somi

IOI is still the best group in PD series, perfect Center (Somi) , Perfect Visuals (Pinky, Doyeon, and Chaeyeon), Perfect Vocalist (Sejong and Yeonjung), Perfect Dancers ( Chung Ha and Yoojung) Perfect rapper ( Mina and Nayoung) and Perfect PENGUIN SOHYE!

😂 I can’t with her reactions lol she’s literally all of us when watching Somi new MV 😮 🍿

I’m waiting for a full IOI reunion within the next couple years. I’d like to see them all contribute to the m/v and song to showcase how they’ve grown as individuals but still so close like they never disbanded.

She’s saying Somi looks very pretty like a Barbie and she reminds her of the actress that playing a movie called ‘Wild Child’ (if you doesn’t know it was Emma Roberts) that’s what she’s trying to tell you.

When adding sub, I just realised that Sejeong is one of the kindest in the world. The way she expressed her emotion and support to SOMI, it is definitely precious. SEJEONGIE, if you read this comment, I will say that you did and are doing a good job! I always proud of you! And everyone, Sejeong deserves our recognition! MY lover~

Aww, I miss I.O.I so much . . . But I also know that their current career paths must make them happy as well~ She looks so happy and proud, I can’t-- 🥺💖

Sejeong's face expression is literally me ahahahaha

She’s proud of makane ! I love their bonds❤️

Haha.. even Sejeong thought that little girl was Evelyn 😂😂 lol

She looks emotional lololol, so supportive. Everyone needs an unnie/friend like her😭

표정이 무슨 외국인 리액션 같음ㅋㅋㅋㅋㅋㅋㅋㅋ 근데 나도 뮤비 보면서 딱 저 표정이었다,,,

Sejeong reaction is my reaction... I was stunned ..

성공한 제자를 보는 교수님인가 ……..

All i can say, SEJEONG is so HUMBLE. She can independently react to other idol's MV, and mention other boygroup or girl group too. Even though she's not in a big company/agency, she is not pressured and she can be real anytime she can hehe! Proud of this girl KIM SEJEONG

I love how there's so much I.O.I interactions/content after the reunion, Olympic athletes still a fan and mentioning I.O.I as their own gg preference, even seeing Somi talking about I.O.I again it's a blessing itself, it's showing that the bond is eternal between the girls, i hope the girls can release an album together again as a gift to the fans♥️♥️

sejeong is us seeing the mv 1st time

I want Sejong to be in a great entertainment 🥺😭

She said she got goosebumps and she doesn't get how somi's doing that hand thing and she said she was speechless during the video and she said 'I didn't curse did I?' lol. And she said somi's so pretty that she look likes a barbie doll (That's a complement in korea) And that somi looks like emma roberts in [Wild Child]

all of I.O.I members supports somi a lot because somi was the maknae of their group before(?) and we all know somi was too soft and friendly like watching this react video from sejeong watching dumb dumb was make my day colorful.

That’s the most natural and honest reaction I have ever seen, lmao the expressions when she with boy…🤣

Same! I loved it. So pretty, everything was so well done😍

IOI is always there to support one another I love it!!💯🥳

She is so humble and with a big hard . I remember she was number 1 in produce season one and in the final Somi took her place. Sejeong was in the jellyfish, such a shitty company that wasted Vixx and Gugudan. They wasted Sejeong. But Seomi ended up in The Black Label and got to debut solo with Awsome music videos,songs and promotions. Who can beat YG style songs? But still Sejeong is so nice and supportive. I love her.

She is so proud ahhh

I rmbr her getting hate back in ioi ,people saying she was jealous of somi and the fans and the media always putting them against each other in every way , and created a distance between them but they always said they were close and sejong always treated the members with such love , i’m sad she didnt get the spotlight she deserved she was one of the best vocals and stable dancers in the team truly an ace she should’ve been very big by now

Sejeong representing all Somi stans. Queen supporting queen

She is so precious

look how proud she issss

she is so cutie 😭😭😭😭😭😭😭😭

Sejeong is the sweetest girl I’ve ever seen 🥰 she’s so kind. I’m a proud fan ❤️ n I just can’t wait for her new drama

Love how pure her reactions are lol 😂

Proud mom😭❤️❤️

Sejeong is so cute and likes a mother suddenly realised her daughter growing up and falling in love, then donno how to react xD

If Sejeong says you're pretty... you've made it.

Does Sejeong have her own KZfaq channel? KZfaq needs her! 😍

sejeong really genuine 🥺 i love her so much

The proud mom reaction 😊

Love em both.

귀여운 사람들🧡🧡 IOI 멤버들을 정말 사랑해유ㅠㅠ

Kim Sejeong supporting her friend - and fellow IOI member. Kim Sejeong how can you be sooo awesome?? To me she is ultimate girlfriend material ❤❤❤

00:00 : She’s going to watch the ‘dumb dumb’ M/V and is searching SOMI online 00:10 : ‘So- So-Mi’ 00:17 : ‘Dumb dumb! Yay, OMG (or something along the lines of ‘Yay, let’s go’??)’ 0:28 : ‘Is Evelyn comming out?/ Is that Evelyn?’ (Evelyn = SOMI’s little sis) 0:46 : ‘Okay, one... (she’s counting down with the yt premier thingy) Tada!’ 1:00 : ‘Oh, so it’s not Evelyn’ 1:20 : ‘I just got goose bumbs (is that written correctly?? 😅)’ 1:35 : ‘NOoo!? 😮’ 1:41 : ‘How do you do this?’ 3:34 : ‘No, I mean, (I don’t really know what she’s saying when she’s stuttering but she was so into the M/V that she asked if she didn’t say anything weird while reacting (I think))’ 3:52 : ‘Just now I don’t really remember (what she said/ did) when I watched it’ 3:56 : ‘It’s insaine/ crazy!’ 4:01 : ‘Somi... it’s insane! How is she this pretty? I mean, she’s a doll, a doll!’ 4:08 : ‘I mean, the from the first time you see her, that..., wow!’ 4:13 : ‘Normally, I don’t really call people/ I don’t really like calling people a Barbie doll, but this (= SOMI) is actually really a doll.’ 4:21 : ‘It’s a Barbie doll.’ 4:28 : ‘So pretty. I mean first of all the song is also so good and that dumb dumb (the move) is good. The ‘dancing on your head’ lyric/ it’s dance move is good...’ 4:43 : (I don’t really hear what she said. Something like: my Words don’t come out/ I don’t what to say OR this doesn’t make sense as in: this is crazy) 4:46 : ‘For now/ first of, first of, she is normally already pretty. Her body is so (makes curves with her hands) skinny. It’s insane. What is she this pretty?!’ 5:00 : ‘ I...(something, something) the movie that I used to like the most was a movie called ‘Wild Child’. Do you know the movie ‘Wild Child’? Among the High-teen movies (= Those early 2000’s movies like Clueless, Mean girls etc.) it’s really known. It’s called ‘Wild Child’. Shall I/ we look it up? W-i-l-d C-h-i-l-d (searches for the movie). This is no joke this is a movie that is have seen over like 20 times. Because I really like High-teen (movies).’
