Rookie boy group ATTACK has released their teaser for "Hello Hello"!

The song sounds like it's going to be a sad song that talks about love. The MV seems to accentuate the sadness with dried flowers and an actress who cries while clutching her handkerchief.

ATTACK debuted last year, and consists of members Jiyoung,�Sunghwan,�Jonghoon,�A, and�Changwoo.�ATTACK includes two former�KINO members (Jonghoon, Sunghwan) as well as former�SOS members (Jiyoung, Changwoo).
