You and Jaehyun were once a couple, but on a random wintery day of december, both of you decided to break the relationship after spending a whole 7 years together. Since high school.

Now, even after 3 years, you're still clinging onto the memories you've made with him before even though you've tried to erased it.

All of sudden, you saw him at the same hotel you're staying at for a vacation at France.

Will both of you fell in love with each other and redo it all over again?
