Choi family, a powerful business family in China and is also Wooyoung’s parents' best friends.

Wooyoung’s mother died in a car accident with his siblings, his father did everything to make him happy and he always protected him.

Unfortunately, he died from cancer a few years later. His last wish was for Wooyoung to get married to someone who'd protect him. And make him happy.

The Choi family granted it and married Wooyoung to their eldest son, San, but he was cold to him and always busy, like he hated him.
