Need help identifying a song.

It's not on the OST, and they're just actors so it's not a cameo like Fiestar. Been driving me crazy because I cannot find this song.

ahh~ i gave up what's the tittle of that song.even on CD tracklist, i couldn't find that song (maybe that song is going to be a main tittle of new group. i don't have any idea whats the tittle ) i even googling that chorus part. ayiyaiye aiyaiya )

Yeah I think I'm going to have to give up too, was hoping someone might recognize it. Maybe you're right, could be an unreleased song, but that doesn't seem likely to me.

I am more interesting in the song now because no one know it..

You guys had me obsessively looking for this song!!!! I typed in the lyrics and can't find a match. It is a good song!!!
Hopefully it'll surface somewhere.......soon!!! >___<
