With the sudden departure of their Japanese member, Tomo, AST'1's leader, Jungjin surprisingly announces the group's breakup on their official Daum fancafe.

AST'1 was a part of DSP, the same company that created SS501, KARA, and Rainbow. They released their first single "1, 2, 3, 4, Back" in 2008 and their 2nd single "Dynamite" earlier this year.

The group is perhaps best known for their member Haiming, who had a cameo as Jihoo's friend in the hit drama of 2009, "Boys Over Flowers." The group also contributed the song "Yearning Heart" to the official "Boys Over Flowers" Soundtrack.




The following message was posted by Jungjin on their official daum Cafe. (Eunice is the name of their fanclub).

오늘 마지막으로 ast1의 리더 정진이가 유니스에게 보내는 글입니다.
우선 너무 놀라셨을꺼에요
루머 ..? 라고 떠돌던 말들이 사실화된건 맞습니다...
우리 유니스의 ast1은 ... 마음 한곳에 접어두어야 할꺼같네요...
ast1은 해체되었습니다
해체됐다는 사실을 알리기가 힘들었습니다..
저도 믿기 힘들었습니다...
멤버들 다 마음 고생도 심했구요..
저희도 이렇게 힘든데 ....유니스에게 알리기가 두려웠구요 힘들었습니다
이제서야 이렇게 말씀드네요...죄송하고 미안한 마음뿐입니다...
현재 멤버들은 각자 생활하면서 잘 지내고 있습니다 ..
각자 자신의 위치에서 열심히 살고 있습니다
저의 가족같았던 ..동생들.. 친구....
무대위에서의 AST1를 응원 하듯이 따뜻하게 바라봐 주셨으면 좋겠습니다
AST1의 이름으로 다시 무대에 오르는것을 힘들지만..
다시 저희들이 무대에 올랐을때....
지금과 같이 응원많이해주시고 사랑해주세요 ...
이글은 ... 다 쓰는 동시에 ...AST1의 리더는 원래의 제 자리로 다시 돌아가있겠습니다..
그동안...너무 고마웠고 감사했고 ...힘이됬고...사랑했습니다..



Roughly Translated:

Entry from Leader Jungjin to Eunice:

First, you'd be too frightened
Rumors...? are actually true.

A’st1’s Eunice… it seems like we have left our heart in one place…
A'st1 have disbanded.

It was hard to decide whether we should disband or not.
It's also hard for me to believe.
The members are also suffering.

It's hard for us too...it's really hard to inform Eunice.
Now i'm just going to say that...Sorry, i'm truly sorry.
Current members can have their lives while doing well ..
You are like our families....our younger sisters/brothers...our friends...
I was really glad that you cheered for A'st1 warmly and watched over us when we were on stage.
Eventhough it will be hard to comeback on stage as A'st1...
when we'll go back on stage...
give us a lot of love and cheer for us like you are doing now...

this writing... while writing it ...AST1s leader returned back to his place

During this whole time, thank you all, you guys gave us strength. We love you.
