Taehyung notices everything. And by everything, I mean EVERYTHING. The nervous twitch of someone about to go on stage, the irritated look of teachers, and even the emotional distress of people who just broke up. He loves spending his time observing people. So when a new kid Hoseok arrives, he's instantly intrigued in the boy, but he disappears mysteriously? Only to turn back up years later? Now Taehyung was really intrigued. 

Hoseok is the new kid whom everyone loves. He's funny, sometimes sassy and smart. He gets frequently confessed to and asked to hang out, but denies all the invitations. There's just one thing he'd love to do at home more than anything. He suddenly swtiches schools for family issues and meets an old friend from long ago. Taehyung?

What happens when they finally meet and form fireworks? What's holding their love back?
