it's because they're successful now..i think when they still new they doesn't eat much..its proven when hyomin confess she doesn't allowed to eat much in the early episode of invincible youth..
i almost watch all t-ara performance..^^..they almost perform without any mistake that can be seen in the performance..except hyomin mistake in inkigayo..^^..
definitely agree..i fall in love with this song after the first time hear it..but i don't understand why many people find this song annoying..^^..whatever..the important thing is i like the song..
because T-ara member is so busy..they have individual job too..so if 1 or more of the member have a same individual schedule with the group schedule, they still have enough member to do the group schedule..
