Sometimes, you have to accept the fact that what is done is done. 

Sometimes, you have to accept the fact that what is said cannot be unsaid.

Sometimes, you gotta accept the fact that certain things will never go back to how it used to be.

The past cannot be changed, forgotten, erased or edited. It can only be accepted.

A story where Jongin couldn't accept his 'girlfriend' for who she is. 

Yoo Se-Na is a girl who is pretty much oblivious to what happens around her. She does not realize that Jongin is uncomfortable with her because Jongin does not  love her. 

How would Se-Na take it when she finds out how Jongin actually feels? Does Jongin really not love her?
