  1. I love them so much IOI fighting!!!

  2. Somi should be the Lead Dancer, Lead rapper, Lead Vocalist, Face of the griup, Center and Maknae. 👍

    • wtf shes not even that good- and sejeong, jieqiong and doyeon are all prettier than her imo

      • ioi will not be ioi without somi. why compare?

        • think before you type

          lol what do you mean I.O.I will be I.O.I without somi? Somi just became that popular because she’s from jyp, see? when she joined sixteen she didn’t win because also of lack of votes since her competitors are also from jyp. Now when she joined produce 101 she got alot of votes from jypstan since she’s the only contestant that’s from jyp. Don’t tell me that she won because of talent? yes she’s talented but how about the others that’s talented than her? if she won by talent then others couldve gotten in 1st place because don’t tell me she’s the most talented there?

          I.O.I without somi is nothing? lol look at their songs, somi barely even get a line.

      • dude keep your opinion for yourself.Their all pretty so just stop it

    • if that happens ioi will not be group and somi will just be a solo artist

    • Face of the group and center is the same title.. It show that sge was the most popular in IOI

      • Face of the group means you’re the visual aka the prettiest in the group.
        While Center means you’re in the center in the performance.

        i hope you would understand this.

        • Being the visual means you are the visual. The face is the center member or the most known member. In sistar for example, hyorin is the face but Dasom is the visual.

  3. [INFO] Mina and Doyeon was bron on the same month, same day and same year

  4. q bire’ ioi..jgn coba ngalahin twicee
    awass lohhhh,,dsar plagiat

    • ioi plagiat twice? darimana mba, ngomongnya ngaco bhak.

    • Nur aishatul amani

      Oiiii….bila masa ioi itu plagiat sama twice….kamu itu tiba2 datang…terus ngomong macem2 ‘about’ ioi….ioi itu asli…..twice juga asli….gak meniru sapa2 kok….jgn tuduh sembarangan okkkk…tuih..

  5. Doyeon high is 172cm not 170..

  6. I’m really curious on how RedLine Kim So-Hye did it. I mean, during the competition… she did not do very much. And she’s in F. But then, congratulations.

  7. So-hye did the best that she could. It’s the people’s decision not hers.

  8. Am I the only one who thinks that Sejeong (who is adorable by the way) looks like a female S.Coups? When she smiles, it’s especially creepy hahahahhahaha.

  9. left-right : chaeyeon, Zhou, mina, sejeong, somi, nayoung, sohye, chungha, yoojung, yunjung and doyeon

  10. Jung Chae Yeon, already left i.o.i and returns back to DIA? feel so sad to hear that…unacceptable!

    • wait wait, she’s not leaving yet, she still joining I.O.I but also returns back to DIA, like being in two groups

  23. somi is same age with me but she have different life because now we should be a student and still study but she is entainer and very popular..

  24. chungha is lead vocalist not sub vocalist

  25. omg!!! wait a minute….is that yoo jung from ASTRO BREATHLESS MV???she is so cute 🙂 btw, somi is in the same age with me 🙂

  26. wow Birthday Jeon Somi same with me .. she is only a year older than me … yeah haha..but she very talented and pretty.. ^_^

  27. Somi 2001? Yaampun gue kira udah kuliah haha. Muka dewasa amat dah
