"Jung Daehyun always wears a mask. Always. His upper face is so handsome. His lower face couldn't be that ugly, right?"

Kim Miwa always wondered why Daehyun wore a mask. He was already so handsome, so how ugly could his lower face be, right? But since she was too shy to talk to him face to face, she sent him a note..

A note that led to friendship...

And soon led to love.
