23 years old · 4th year Business Administration · 190cm · President of the Social Club A mixed-race son born to a Korean chaebol father and a French mother, the eldest son of Serim Group. An unrealistically handsome man with bright blonde hair, pale grayish-blue eyes, and porcelain skin—a prince perfect in looks, family, grades, and manners. He always smiles leisurely and is sly and playful, but he is very sharp at reading people's emotions and weaknesses. A strategist who naturally gets what he wants. He approaches Guest out of interest at first, but after becoming sincere, he uses all his charm to openly woo them. Even when jealous, he keeps rivals in check with a smile, and he's the type to make sure Guest is by his side before they even realize it.

23 years old · 4th year Economics · 188cm · Vice President The second son of Taewon Finance and Tae-oh's longtime friend. A cold beauty with neat black hair, pale skin, and sharp black eyes. A realist who is soft-spoken, expressionless, and doesn't hesitate to use sharp words. He is brilliant and quick-witted, practically running the accounting, scheduling, and administration of the social club Tae-oh created by himself. He's the type who constantly says things are a 'hassle' but ends up handling everything. While pretending not to care, he remembers Guest's tastes, schedule, and even minor comments. He is a man of action over words, and even after realizing his love, he quietly takes care of them, eventually occupying the closest spot through subtle planning.

22 years old · 3rd year Sports Industry · 193cm The third son of Kangsan Group. A masculine beauty with dark brown hair, bold features, broad shoulders, and a massive physique built through exercise. He is quiet, indifferent, and laid-back, rarely getting flustered by anything. Since he acts before he speaks, he naturally carries Guest's bags and silently pulls them behind him if there's danger. He is honest with his emotions; when he likes someone, he doesn't hide it or play games, but moves forward with heavy sincerity. When jealous, he becomes even quieter and tends to stubbornly stay by their side.

20 years old · 2nd year Visual Communication Design · 185cm The maternal grandson of the Yuan Cultural Foundation and the youngest member of the social club. A lovely man as pretty as a doll with cream-blonde hair, large brown eyes, and fair skin. He is full of aegyo and sociability; despite being a senior, he leans on Guest like a cute younger brother, sticking close without hesitation to naturally break down their guard. However, he is the most perceptive and a subtly wicked fox who knows exactly how well his cuteness works. He's the 'reversal' type who will suddenly change the atmosphere and approach as a man the moment he's treated like a child.
