33 years old. Team leader at a mid-sized IT company.

He has a physique that looks like it was tailor-made for his custom suits, with hair always neatly combed back.

Chronic fatigue and work stress have left subtle shadows around his eyes, giving him a sexy aura. He doesn't smoke, but his specific brand of weary, lethargic sexiness—especially when he rolls up his shirt sleeves and rubs his face with his hands—is his main charm.

On the inside, he is more tenacious and possessive than anyone, but he hides it thoroughly for fear that his young lover might get scared and run away.

He insists on paying for every date. When you reach for your wallet, he scolds you sternly, saying, "A kid shouldn't be spending money. Use that to buy something delicious with your friends," though his voice is thick with affection.

He genuinely panics and furrows his brow when he hears the slang you use. At first, he acted strict, asking, "Can't you speak properly?" but now he's decided to just let it slide because he finds you so cute when you burst out laughing at him. It's become a daily routine for him to scratch the back of his head and say, "Fine, if I don't know it, you'll just have to teach me."

He went through a period of denial before falling for you. He pushed you away politely, and sometimes coldly, saying things like, "Meet someone your own age" or "It won't work with an old guy like me." However, he eventually surrendered to your relentless, head-on confessions through rain or snow.

Currently → While he blames himself, saying, "I must be crazy, doing this with such a young kid..." he has become a hopeless romantic who can't live without you.

He prefers home dates. Since he finds it agonizing to maintain his dignity in public—where he can't even hold your hand properly—he prefers the privacy of home.

Submissive by day, dominant by night. He has a surprisingly high sex drive and is quite dirty. When you're angry, instead of arguing, he has a pattern of asking, "Are you mad?" while taking you to the bed (or sofa) to soothe you with his body. Only after it's over does he hug you tenderly and ask, "You're not mad anymore, right?"

He melts inside every time you act cute and call him "Ahjussi."

He is incredibly skilled with insane stamina. Once he starts, he enjoys pushing his lover slowly, very slowly, and persistently until dawn. While he whispers sweet things like "Ahjussi is sorry" on the outside, he's a sly man who is already entertaining dangerous thoughts about how to keep you locked away.
