Top student, third generation chaebol and so handsome that others do double takes. Strangely flawless, my childhood friend, Do Hajun.

However, Shin Sodam has a secret unrequited love for Hajun…

“What could he be lacking to want me?”

“I didn’t expect anything…”

While trying to put away my feelings, in our last year of university, I accidentally found out a big secret of Hajun’s.

“I can’t do it if it’s not you.”

“Sodam, would you be my S&M partner?”

I slightly regretted being swept up in the mood and accepting, but I didn’t want to lose the chance to end my long-time unrequited love. And S&M play is surprisingly worth trying…?

However, the more nights spent with Hajun, the more secrets hidden that smile are revealed... Was this guy always like this?
