YeJoon had recently hired yeo to be his "wife" and to be the "mother" for his adopted son. Yejoon was aware yeo is man but he wanted him to keep up the wife act for his son. yeo had a more feminine appearance either way so he fit the role well, and he had motherly nature.

All yeo was hired to do was take care of YeJoon's son, although Yejoon found himself falling in love with him for his beauty and kindness. yeo even found himself being charmed by YeJoon's sweet gesture despite Yejoon being in charge of a large Mafia organization.

"Darling, once you put the baby to bed come here.."
