Lee Sungyeol made a promise.

His promise is to love her.

But in the end, 

Can he still keep his promise?

Or he have to let her go?

~

       Lee Sungyeol knew since he was a child that a promise should be kept.  He knew that a promise should be kept because the other person is still waiting for that promise. Sungyeol knew that he loved her and she loved him too. But what if the circumstances doesn't allow him too keep that promise? Is he going to keep holding on or he'll have to let her go?

           "Sungyeol-ah, wherever you're right now, I know you are waiting for me too."
