It all started in a small café..

Where a teenage guy who was working there temporarily, meets a teenage girl who often comes there to buy a hot cup of chocolate latte and goes to her particular corner at the back alone with emotionless face.

“Why don’t you smile?”

“Because I don’t want to. And because I have no reason to.”

“And why is that?”

“Why are you even asking me questions? I don’t even know you.”

“My name is Park Chanyeol.”

“Alright then, Chanyeol. Why would you eve—”

“—Smile for me.”
