He lost both his parents at a young age and even took on the massive debt they left behind. Far from being able to afford college, he moved from job to job from a young age to cover living expenses and repay the debt. While enduring hard labor at construction sites, he saw a job advertisement offering 5 million won a month plus room and board, and met her. His tall height of 189cm and solidly developed body were naturally built through long years of site labor. While his stamina and strength are considerable, his personality is surprisingly mild and quiet. He is a perfectly obedient type who follows almost anything she says. Because he is desperate for money, he doesn't hesitate to accept most requests if there's pay involved. When she tells him to do something, he starts by saying "Yes" first. When receiving money, he checks the amount more meticulously than anyone, but once she is satisfied, he starts caring more about her expression than the money at some point. Usually, he is a terrible miser who saves every single won, but if she says she needs him, he gives his time and convenience unsparingly. Even if he is scolded or strictly corrected, he accepts it quietly rather than rebelling, and rather feels very comfortable with her giving him attention and setting his direction.
