Who is your OG School bias?

Latest Korean comeback:

Who is your OG School bias? Do you know more facts about them? Feel free to comment below. 🙂

About the author


  • evening

    my bias is Park Hyunjin but they are all tallented

  • Charlene Cachero

    Bruh, I’m literally the same age as them but look at me, Imma potato

  • Ann Vina

    are you sure they 14 years old(KOREA) . gosh they are so talented rappers. Another dongsaeng kpop idol that completey breaking heart. i’m 19 they ARE 14?!!!

  • YourAss

    Wait they r born 2005? arent they 12/13?

  • Eny

    I’m really sorry about Achillo’s attitude. He calling RM a Rap retard was really disrespectful for a 12 years kid. RM has a hug career behind, which Achillo should at least respect.
    I’m really disappointed because I was interested in this new band and he was my bias

  • dphoeurk

    They’re just a year younger than me I like oppa not Noona UGHH!!!

  • Pearl Amour

    Im questioning my life rn. They r the same age as me and Im just sitting here watching kpop all day xD

  • Danica Marie Go

    sooo im now 4 years older than them i wanna cri

  • ѕтreαм cαllιɴ’ ! 📞

    the namjoon thing is fake, he didn’t actually say it.

  • wenny

    it actually is true. he posted it on his Facebook that RM is a rap retard. then he even replied on his Facebook that is his own opinion and it’s not a big deal if he considers RM as a Rap Retard

  • Angel King

    Technically yes, but in Korea or better yet in their Korean age it is 15. In Korea when you are born you are already one years old and I think they also add another year when it’s new years.

  • Wondergal

    Allkpop is never a reliable source lmao

  • GA JR The Great

    Achillo should be careful of what he says(Or posts anyways), this could damage the image of the group. I’m not trying to be mean or anything, I’m just saying, if you’re a rookie and have little to no experience in the Idol world, you should keep your opinion and thoughts to yourself if you know it’s gonna get you in trouble. But I really do hope for this rookie group to have a successful and bright future. Fighting!

  • Parkdatass Jimin

    actually in Korea you’re just one year older than your normal age so they are 13

  • Riannah M_

    actually Achillo didn’t actually say that allkpop isn’t a very reliable resource for information. Achillo doesn’t have a facebook account it was some kid pretending to be him.

  • quim

    allkpop announced that, but it was a fake news, actually someone used Achillo’s name to post that hateful comment. that person even admitted it.
    some people, really………….

  • YourAss

    achillo doesnt have any social medias.


    Achillo is born December 23 2005

  • Bamie

    No on new year we get one year older

  • Bamie

    That’s weird and disgusting don’t say that about a minor, I’m their age and all of them are older than me and I’m half Korean half black but I don’t say that about them I honestly don’t even like the word Oppa because people use in a disgusting way

  • KProfiles

    Thank you for the info, it’s much appreciated! 🙂

  • jes

    park hyunjin is born on may 24 2005 :’)

  • taehyungie:) 김태형

    If you do the math (current year + year of birth, in this case it’s 2005, then add 1) you will end up with 14. So all three of them are 14 in Korea.

  • dphoeurk

    When you think about it its not that weird. I’m 1 year older than them and I don’t date guys younger than me. I wasn’t using the word oppa in a sexual way and I wouldn’t like the idea of being a noona in a relationship. And it’s cool you’re Korean, I’m Chinese-Cambodian.

  • 혀선 언니

    first of all, why did you even think about dating them? sure your first comment said nothing of the sort but through my limited sight due to the internet’s lack of giving comments emotions, you look like you’re annoyed because they’re younger than you and you think it’s spunk and cute if you date someone older.

  • Bamie

    But why would you say it like that ? When you wrote it out you made it seem you were really upset about that, and no hate I know there isn’t a lot of kpop idols that are young but it makes me feel weird bc of the way people miss use Oppa and it’s werid that’s why I said it was werid and disgusting. Don’t mind me, just my opinion

  • Bamie

    Oh I know, I was telling them we get a year older on new year and yes they are 14 in Korean age

  • Clara711

    Wow… youngest Kpop singers to exist.

  • KProfiles

    Thank you for the info, it’s much appreciated! 🙂

  • Eh Sue

    Woochan😍😍but we’re on the the opposite sides of earth from eachother😭

  • Chrystalyn

    Wtf Im 1 year older than them ahdkabsjsbdjs I feel old😂

  • jes


  • ᴍᴜʟᴛɪғᴀɴᴅᴏᴍᴇʀ ᴀғ

    lmao same 😂😂😂
    I’m finally a “noona” 😂😂😂😂

  • GA JR The Great

    How can you be so sure that it wasn’t him but just anotheri kid pretending to be him?

  • Angel Christine Medina

    I’m just months older than Hyunjin and Achillo lol


    @glinkajimenezakagajr:disqus Every trainees under their companies doesn’t allow to have any social media accounts and also, the one who spread the fake news apologize coz it was fake. Check it out on twitter.

    =He’s real name is Hyun Seonoong (I don’t know why he used to be called ACHILLO all the time. It is stated on twitter and on the controversy conversation on facebook.)

  • Kitty TFM

    Nope, G.Story (debuted in 2010, unofficially disbanded soon after) were much younger. Their debut was actually the reason that broadcasting companies added new regulations.

  • Clara711

    What your native language @Eny

    I’m really sorry about Achillo’s attitude. Calling RM a Rap retard was really disrespectful for a 12-year-old kid. RM has a huge career behind, which Achillo should at least respect.
    I’m really disappointed because I was interested in this new band and he was my bias.

  • abigail hoeskstra

    Omgsh baby stans are all in these comments, im glad that y’all finally have a group that is your age!!! Im an ’01 liner so all the groups debuting right now are either my age or younger than me so its weird being a noona lol. Im so used to groups like shinee and bts who have members almost 10 years older than me so i cant imagine what its been like for all of you!! Another group that is around this age group is called BOYSTORY and they are from jyp. Also a great group 🙂

  • eunyou03

    oml. I’m 2 years older than them. they are the same age as my brother. omg that feels so weird. Imagining my younger brother as an idol. please no.

  • Leysia

    Freaking heck man…. they are a decade younger than me. Talk about feeling old…

  • Mei

    Achillo and Hyunjin released a new song called Bucket list still under the og school project

  • Naé-Naé Productions

    HyunJin has braces!
    it’s seen quite easily in their Vlives and in the OGZ MV Making video
    Woochan is also currently living in LA
    (i forgot what show it was announced on but he sent a video of himself to those who were on SMTM6 saying he was staying in LA and it wasn’t long ago he announced it)

  • Jangmi Moon

    When I saw when they debuted it made me smile cause they debuted on my birthday

  • Toria San

    He was nt living in LA but traveling during his vacation but he came back to participate in the next video (actually is a one ep special bit or had 2 parts broadcasted separately) of the smtm6 especial nd killa tried to talk to him in english but woochanie laughted saying he didn’t learn much yet, he got way taller thought

  • Hyunjin really likes blackpink, especially Rose

  • It’s a bit sad that Hyunjin and Jongseop couldn’t be be together 🙁 They had good chemisty. Now Hyunjin is training in Starship and Jongseop in YG (and is currently in YGTB, but it seems unlikely for him to debut yet)

  • Raynanana

    Awww thx haha UWU

  • CandraDee

    This is late, but I’m assuming it had to do with the death of SHINee’s Jonghyun. He passed away two days before their original debut date so they probably pushed it back do to everyone mourning.

  • I.M

    I’m only 1 month older then the youngest one

  • Rea

    Achillo’s birth name is Hyun Seonoong or Hyun Sunwong, but this is most likely to be a rumor.
    Achillo – 아칠로
    Hyun Seonoong – 현서눙
    Hyun Sunwong – 현순웡

  • They released one bop and fell off the face of the earth. 🙁

  • Rea

    b o n u s f a c t s
    Jo Woochan’s height is now 171 cm/5’7, please update. (However I don’t know where I saw it)
    Achillo birth name is Hyun Seon Woong = 현선웅
    Achillo and Hyunjin had a comeback last September called “Bucket List”
    I saw that Hyunjin has braces, however they are transparent and it’s not kinda obvious.

  • Yeet_Kpop_life

    What was the tragedy??

  • ✨💘✨

    it was around the time when Jonghyun passed away…


    I finally found out about the truth that it was false

  • Kang Daniel

    You guys should update this page

  • Lucas_22

    Yass finaally 2005 im heeerrrree

  • Ish Nami

    e and lo ave te sae y

  • 柳渡なべ (Ryu Watanabe)


  • 柳渡なべ (Ryu Watanabe)

    Now they’re like in their 20’s (G. Story), and Chinese jyp group boy story is younger (2004 – 2007) same as yuehua boys (2004 – 2007). But the youngest record goes to LiSo/Little sonyeondan (2005 – 2009) under Rainbow/RBW, just look up their song “Hit Me”.

    I don’t know if Na Ha-eun counts, she’s an online dancer sensation and is a ’09 liner. While me here is a ’06 liner and is a stale potato.

  • Ik I watched the show 🙁 I knew from almost the beginning he won’t make it. He got so little screen time and is really young so YG probably “save” him for next gen YG bg
