Dokgo Ma-te is the most beautiful man in the world. He is also an ambitious man and wants to make a lot money using his beautiful appearance. When he meets Hong Yoo-ra, the ex-daughter-in-law of a rich family, she recognises his ambitions and becomes his mentor. But when the poor, but adorable Kim Bo-tong surfaces with a huge crush on Ma-te, everything changes.
