Y/N and Hakyeon were best friends when they were little. They would do everything together and they were what you call inseperable. Until Hakyeon was informed that he was going to move to the States, devastating both of them.

He left when they were six and they made a promise - to never forget one another and that he will come back for her.

However, shortly after he left, in an unfortunate car accident, Y/N lost all memory that she had before she was six, therefore forgetting completely about Hakyeon.

Currently at the age of seventeen, Y/N is loving her life. She has fallen for the student president of the school, Ken, and she has decided that she is going to confess to him. Her best friend Hongbin seems to agree with her and with a push, she gets to confess. Her life is exactly how she wanted it to be.

Although, when someone comes back and tries to push Y/N to remember something that she has no recollection of, her perfect little life, is about to get a whole lot messier.
