Kunpimook Bhuwakul has a little crush for his senoir named Mark Tuan. He's too shy to confess his feelings directly to the older and it makes him annoyed. His friend, Kim Yugyeom suggest that maybe sending him love letter everyday would work. So Bambam did. Until a day comes when he saw Mark secretly slides red letter inside his locker. He's really happy that time and expected too much but got disappointed when he opened it.

Hey! Kindly read my letter for you. I'm such a coward to confess my feelings so I guess sending a letter would be better. I'm Mark Tuan and I really like you Kim Yugyeom-

"Oh, really?" Bambam said as he crumpled thep aper.
