Hmmmm... I have a hard time picking between Lupin, Mister and Secretly Secretly. But if i must, I'd have to go with Lupin because they look so good in the MV
Honestly, no I wasn't an immediate fan. Back then i wasn't into Kara or K-pop in general. Until I started listening to K-pop and got into Invincible Youth. Then Kara caught my attention.
