This Chef? He's Gamble King!

Feng Qian, a gambling master, fulfilled his dying master’s wish by protecting the Du family and marrying Du Yan for three years while hiding his identity. Despite his devotion, he was treated with disdain. As the agreement neared its end, Du Yan was framed by a friend, putting the family in danger. Feng Qian stepped in, used his skills to save them, and then left. Only after he was gone did Du Yan realize his worth and desperately search for him.
