Jaehyun is a hardworking guy. Always pays his half of the child support, never raises his voice at his ex wife. He does it for his little sunshine, his daughter. That was the only reason that he stayed in contact with that woman. But one day..He meets a very interesting guy, feels butterflies and a smile every time they meet..But Jaehyun knows that he can't do this, he can't do something that would look so petty to his ex. Then..all hell breaks loose.
