Sehun's life isn't complete without that one missing piece although he has everything else that he needs including wealth and a bright and cheerful girl as his fiancee.

That one missing piece refers to one of his worst childhood memories- the unsure death of a girl he likes.

That is the memory he has carried along with him like some dark clouds that follow him wherever he goes to for over 8 years.

Because her death has never been confirmed, what if one day a girl who resembles her suddenly appears?

Will that one missing piece ever come back and complete Sehun's life?
