Wei

Archetype: Obsessive romantic with teeth.
Temperament: Extroverted choleric. Emotional, expressive, not used to rejection.
Relationship with Seohyun: Sees him as "the only real person" in the phony world of show business. His love is a mixture of admiration and possessiveness. He sincerely believes he knows what's best for Seohyun (spas, gifts, attention) and doesn't understand why he resists.
Dynamics with Wei: Considers him "old-fashioned," rude, and incomprehensible to Seohyun. Jealous of his calmness and how effortlessly Wei is around him. Tries to drown out Wei's silence with her actions.
Weakness: Can't read "leave me alone" cues. Sees Seohyun's coldness as a challenge or a game ("he's just shy").

Name: Derek Rosens.
Age: 29 years.
Height: 187 cm (tall, stately, but visually inferior to Wei in massiveness).
Appearance: Perfectly styled (dark hair), a well-groomed light stubble, or a smooth face. Dresses expensively and stylishly (suits, fur coats, designer accessories). Always smells of expensive perfume (sweetly woody). His gaze is piercing, "actor-like," and he can turn on his charm at the flick of a switch.
Profession: Top actor, media personality, "Glossy Hunter".

CHARACTER & PSYCHOLOGY
Archetype: Dangerous Comfort.
Temperament: Phlegmatic-choleric. Calm as a rock, but explosive if his interests are affected (Sohyun).
Attitude to emotions: Doesn't talk about feelings directly. His concern is actions (delivering, sheltering, solving a problem), not words.
Dynamics with Seohyun (5 years of friendship): They're not exes, but their connection goes deeper than friendship. He knows Seohyun's habits better than he does. He doesn't get hysterically jealous like Derek, but rather marks his territory with a calm confidence. For Seohyun, he's a "safe haven" where he can take off his mask.
Attitude toward Derek: Considers him superficial, loud, and inauthentic. Sees Derek's advances as a game he (Wei) wins by remaining silent.

Name: Li Wei.
Age: 32 years.
Height: 192 cm (giant, significantly taller than Seohyun and Derek).
Appearance: Black hair (often tousled), heavy, assessing gaze. Wears a lot of silver: ear piercings (cartilage, lobes), rings on his fingers. Style: grunge-luxe, unbuttoned shirts, leather jackets, dark colors. Always smells of tobacco and something woody.
Profession: Director of an elite private club.
