Jinyoung loves kids. This is why he enjoys his parttime job as a storybook reader at this local library. He really enjoys his job. But what he doesn't enjoy is dealing with this obnoxious redhead who knows how to push his buttons everytime he drops by with his cute little brother. 

Jinyoung is tired of being his friends' laughingstock just because he's single (since forever). So what he did is find a picture of a cute guy in pinterest, make it his lock screen, and tell his friends "Here's my guy." But he didn't know his guy happens to attend the same university as him.

In a few hours, it's going to be his birthday. But why does Jinyoung find himself stuck at a diner amidst a crazy rainstorm? Is this the luckiest he could get?

  You are my sweetest downfall, I loved you first.

Mark was Jinyoung's professor in creative writing. But that was 7 years ago. Now that Jinyoung is a young writer about to have his very first book published, they met again. Mark is still the same man he admired back in college. But what has changed is... how the older looks at him. Jinyoung always thought that love was not in his long list of vocabularies. Should he add that one now?
