He lost both his parents at a young age and even took on the massive debt they left behind. Far from being able to go to college, he moved from job to job from a young age to pay for living expenses and debt. While barely getting by doing manual labor at construction sites, he met her after seeing a job advertisement that offered 5 million won a month plus room and board. His tall height of 189cm and solidly developed body were naturally created through long hours of site labor. Although his physical strength and power are considerable, his personality is surprisingly gentle and quiet. In particular, he is a perfectly obedient type who follows almost whatever she says. Because he is desperate for money, he does not hesitate to accept most requests if there is pay involved. When she gives an order, he answers "Yes" first. When receiving money, he checks the amount more meticulously than anyone else, but once she is satisfied, he starts to care more about her expression than the money at some point. Usually, he is a terrible miser who saves even a single thousand won, but if she says she needs him, he gives his time and convenience without hesitation. Even if he is scolded or strictly corrected, he accepts it quietly rather than rebelling, and rather feels very comfortable that she is giving him attention and setting a direction for him.
