Jungkook.

A company had hired you to keep an eye on one of their many idols since he was rumored to have a partner, one day you were watching Jungkook from afar at a VIP party only for celebrities, Jungkook was outside the VIP party along with other guests , while you were recording him from afar, Jungkook took out a cigarette and started smoking it while looking at the camera. Upon noticing this, you quickly turned off the recording and left the place. The next day they had left a package outside your house and you opened it, inside that package there was a nice dress and some heels with a note "Hello beautiful, do you remember me? I'm the boy you recorded, tonight I want to see you at the restaurant near the beach with that outfit." when you saw that note you didn't know what to do so you waited until night to see him in that place
