  1. So 89.9% of the article is about Twice and Tzuyu and Chaeyoung? I already feel ashamed with the Kpop world always seeing Tzuyu as this “perfect princess” she’s rude and she’s informal, and you might say she’s just joking but in Korean and Asian culture it’s seen as rude and disrespectful. But I guess you don’t know that since your so caught up in Tzuyu the youngest Kpop idol in history. Well tops, she’s 17 not 16 stop saying she’s 16 when her and my sister are the same age it’s not like she’s 5. Overrated much? Get ready to have a whole new Kpop world with Tzuyu always stealing the show. It’s obviously the Tzuyu show, always ok at 12:00 am to 11:59pm stay tuned

    • ^ I see someone is jealous of Tzuyu ……well, keep being whiny butthurt hater because you know what? She’s becoming even more popular and there’s nothing you can do about it 😛

      • I think their comment might be fueled with a bit of jealousy but..her behaviors are seen as rude and inappropriate here, I’m native Korean and she’s definitely not a polite or respectful girl here, but hey she’s young. I understand it appeals to international audiences so I forgive it slightly..

  2. Where is my baby Sanha and Jinsol and Samuel (Punch) ?

  3. TAEMIN was 14 when he debuted.

  4. Ok, everybody is saying tzuyu is really young cause she’s 16/17 blah blah blah. SNSD’s Seohyun was also that age when she debuted but no fuss? SEVENTEEN’s Dino is also 16/17 but nobody is saying he’s so young here Let’s not forget Sanha from Astro who was born in 2000. Sameul from 1 punch? Please don’t treat Tzuyu and Chaeyoung with extra care and caution when criticizing; just be straight up like how people were to other idols that were around Tzuyu’s and Chaeyoung’s age. I’m not jealous, I’m just stating facts.

    I’m so excited for SEVENTEEN’s comeback and I’m dearly hoping they don’t get out shined by Twice. SEVENTEEN works so much harder and produces their own songs.

  5. they should’ve included BTS Jungkook he’s a talented maknae, who’s good at everything, but seriously some these idols isn’t that really impressive tho, unlike Kookie.

  6. Wow there are some negative comments here when the article is just about some fun trivia, no need to make a fuss about things. But I guess there would always be a dark side when it comes to fandoms :P.

  7. What is with Jinsol of April or with the full group? They are younger as gfriend and jinsol debuted with 14. She was born in the year 2001 and is the Main vocal of her Group.

  8. I’m sorry but like Krystal was younger than the twice members why isn’t she here? lololol
