Soonyoung doesn't own Jeon Wonwoo, the great Jeon Wonwoo everyone wants. But Wonwoo comes back to him, every time. 

It's not about owning, not about being in a relationship, not even about commitment. But Wonwoo only belongs to Kwon Soonyoung. Soonyoung who took Wonwoo's many first times, who knows Wonwoo inside and outside. Soonyoung who understands Wonwoo. 

Wonwoo needs and wants no one but Soonyoung. That, is the ending. But of course, he doesn't always get what he wants. 

By the age of 25, Wonwoo is old enough to understand that he needs more than his needs and wants to keep going back to Soonyoung, for Soonyoung to always be there for him. 

He should've known better.
