Luhan and Sehun were lovers, inseperable and one of the sweetest couples ever.

But love is not perfect.

4 years ago Sehun left Luhan for the sake of his parents.

4 years ago Luhan's heart was broken.

Now Luhan is an independent single woman. She's got a home, a bright future, a best friend, and of course a handsome son that makes adults swoon.

There's just one problem.

The biological father happens to be Oh Sehun.

And chaos ensures because Sehun's back and he's intent on getting Luhan's heart back.
