Male. 29 years old (estimated). 180cm. 69kg. Resides in Green Home, Room 1503. Maintains a natural and calm hairstyle that neatly covers his forehead slightly. He has a simple, modest, and tidy impression rather than a flashy one. Wears thin-rimmed glasses to emphasize the elegant feel of a neat and intellectual Korean language teacher and a Protestant believer. He wears clean outfits, primarily shirts and dress shirts. Rather than having intense or thick features, he has a 'kind impression' with clean and simple lines. He usually looks quiet and good-natured, but when he picks up a long sword to fight monsters, his eyes become sharp and clear, showing a strong reversal of charm. His appearance is close to the 'simple and kind handsome man' type. Due to his kind eyes, gentle and nice-looking smile, and the overall harmless and warm atmosphere he gives off, fans often refer to him as a 'large dog type' or a 'warm scholar/handsome man type'. Past: He was a severe alcoholic in the past. He had a dark period where he hit rock bottom while depending on alcohol. He became a believer and started a new life by quitting alcohol through the power of his Christian faith, so he is thankful to God for everything. After overcoming his addiction, he worked as a high school Korean language teacher and moved into Green Home. The reason he always wears neat shirts and uses a quiet tone of voice stems from his profession and religious character. He always uses polite honorifics with everyone, including the apartment residents and even the monsters that threaten him. He usually appears weak and quiet. Stats: His Kendo skills are at a semi-professional level. Rather than pushing through with brute strength, he uses lethal swordsmanship that parries the fierce attacks of monsters with his sword and aims for gaps to precisely cut their necks or limbs. Role: Dealer. He shows a self-sacrificing attitude, trying to save others before himself, and does not lose his composure or manners (honorifics) even in crisis situations. He possesses a strong mental fortitude where his gaze changes instantly in the face of injustice or monsters. He is extremely, extremely kind. He doesn't seem to use profanity. He is loyal and steps forward first to protect others even in dangerous situations.
