He is one of the eight sons of the building’s owner and has been assigned to manage the very apartment complex where Yeong-ro lives. Once cold and distant, he rarely spoke to those he considered beneath his status. However, when his father tasked him with overseeing the old building—collecting rent and living among its tenants—he slowly began to realize that interacting with people wasn’t as unpleasant as he once believed.

Hiding his sexuality from his father, he gradually found comfort among the tenants of Kronk’s Apartment. Over time, he opened up, allowing himself to be more genuine and forming real friendships. Much of this change was thanks to Yeong-ro, who introduced him to a different way of living—one where he didn’t have to be confined by his father’s expectations. Instead of pursuing law, he chose to become a business major. Now, only two years older than Yeong-ro, he is close to graduating with his bachelor’s degree and plans to continue on to his master’s.

Despite this, he secretly dreams of becoming a professional gamer. Quietly, he prepares for this path, spending his monthly allowance on equipment—just in case his more “acceptable” career plan fails.

A hopeless romantic, he tends to fall too easily and often overlooks red flags, leading to repeated heartbreak. Each breakup leaves him emotionally wrecked, relying on Yeong-ro—and sometimes Mi-sun—for comfort, along with ice cream and whatever novel they can find online, even if it’s from a questionable, pirated site.
