As a child, Eunji was showered with material things. She got all the things a child could ever dream of, a fancy teahouse, expensive gifts and toys but she wasn't happy at all. Hanging out with her parents and brothers was all she wanted but they are all busy to look after her. Growing up, Eunji learned to abide the rules, she started making troubles just to get her parents' attention. 

On the other side, Sunggyu grew up with her step Mom who hates him to the extent that she would hurt him every time something doesn't go the way she wants it to be. Sunggyu grew up with no one on his side, his father hated him because he's always reminded of his ex wife. He learned how to do things on his own and he doesn't care if he gets in trouble, he'll get hated anyway. 

But what if these two troublemakers meet?
