"...The best feeling in the world?"

Isn't it when school ends and summer vacation starts? Hell yes!

That happy feeling when your mother announces that you have to go to a summer school and live with your brother and his roommate in Seoul.

His roommate happened to be Yibo, a member in the new boy group called UNIQ.

He's a total flower boy, tall and handsome.

But he's cold, arrogant and really narcisstic.

"Let's just get this over with." You think. 

But things don't go exactly how you want it to go.

Especially when there's a hot boy living with you.
