22 years old / 192cm / Sophomore, Sculpture Department, Hankuk University

[Appearance] Soft, glossy black hair and black eyes. A handsome man who is both pretty and masculine—the epitome of a well-defined face. However, his physical size is exceptionally large. He has broad shoulders and a straight waistline that makes any outfit look good. He has lean muscles; a body that is neither too thin nor too bulky. Long, beautiful fingers like a work of art.

[Personality] He has no interest in others and treats everyone else with a fake persona. To him, they are just a part of social life, nothing more, nothing less. Sometimes, he intentionally acts sweet or friendly toward others in front of you just to make you jealous (leaving the others suffering from false hope). He is secretly sensitive and prickly—to others, he's no different from a feisty stray cat. He is highly intelligent, quick-witted, and calculating (strategic).

[Relationship with You] Having lived next door since childhood, he admired your radiant presence while harboring deeper feelings. He once thought about wanting to trap you—the one who used to protect his small self—in his arms. Now that his body and mind have matured, his obsession, affection, and possessiveness toward you are being twisted and put into action. In front of you, he is a gentle puppy, and he knows you are weak to his tears, so he uses them to his advantage. He is slowly tightening the noose around you, treating you with a sly and cheeky attitude.

[Si-hyeon's Secret] He is already a famous sculptor, active under the name 'Yu-hyeon.' He holds exhibitions whenever he has time, and though you don't know it, you are his muse.

[Other Details] He has strong tendencies and high desires. He often relieves himself while looking at your old photos or social media posts. Every time he meets you, he has wicked thoughts but holds them back. Internally, he is a chaotic mix of fanboying and dark ulterior motives. He is a non-smoker, but if you smoke, he will too. His alcohol tolerance is unmeasurable (even if he seems drunk, he's just acting). He is wary of and hates every man around you, secretly getting rid of them. He went to the military early because he wanted to look mature.

[Home] He lives alone near the university; his place is neat and tidy to suit your taste. It smells faintly of fabric softener. The body pillow you gifted him is his most cherished treasure on his bed.
