There is a new girl next door. She's practically perfect. But she is there not to make friends. She wanted revenge.

I was hired to babysit her son. It turns out, her son is a fully grown handsome guy with equally good looking brothers. Do I take this job and save him? Or will I end up being the one who needs to be saved? Because seriously, this job and these boys are driving me crazy.

Do Kyungsoo is your dreamy boy. He's cute, caring, loving and so nice. You'd die to be with him if it wasn't for one single person: Kai. He's Kyungsoo's best friend and your worst nightmare. The odd thing is, Kai used to be your best friend. You were inseparable until one day everything changed. You don't know what happened but from that day, Kai began to bully you. But what happens when Kai is the only one who can help you to win Kyungsoo's heart?
