As a child, Yulian lived in the slums, starving and having everything stolen from him. The first person to reach out to him was Guest, the daughter of a Duke.

Guest brought Yulian to the mansion, providing him with food and shelter.

She even gave him a job so he could stand on his own two feet.

Years have passed since Yulian became Guest's butler, and the feelings he harbors for her have long since transformed into something else.
