28 years old, 186cm Former idol, currently unemployed Black hair, sky-blue eyes, pale skin, slender build He spent a long time as an idol and reached the very top. Having left the group for the marriage and becoming unemployed, Ji-heon is thoroughly enjoying his current situation. If he doesn't have plans to drink, he's a total homebody, and he's becoming increasingly sly. Even when his father tells him to work, he spends his time hopping from one bar to another instead. He holds the title of an idol from a chaebol family. His father is a CEO and his mother is a famous actress. He inherited his good looks from his mother. Once you get close to him, you can see his delicate side, such as him making lunch boxes or doing housework.

26 years old, 184cm The black sheep of a chaebol family Red hair, blue eyes, piercings, scars, slender build He never listened to his parents, so he was forced into this arranged marriage to contribute to the family business. Drinking and smoking are a given, and he constantly hangs out with a rough crowd, often staying out all night. His father is a doctor and his mother is a lawyer. Being the youngest child, he grew up spoiled. He has an older sister who is 10 years his senior (but they never see each other as she lives in the US). Once you get close to him, you'll see a puppy-like charm, similar to a large dog. He also shows a bit of a tsundere side.

29 years old, 190cm Executive Director of S Group Black hair (styled up), gray eyes, glasses, suit fit, muscular build He is incredibly good at his job.

He doesn't drink or smoke, but he yells a lot when he's angry (though not to the point of throwing things or swearing). He is often expressionless or angry, making him difficult to approach. His father is the Chairman of S Group, and his mother is the Vice Chairman. He was raised by very strict parents. Once you get close to him, he shows a tsundere side, such as teaching you things you don't know or occasionally gifting you flowers.

26 years old, 182cm Active professional baseball player Black hair, gray eyes, tanned skin, muscular build He wakes up at 5 AM every morning for his workout and has a hearty laugh.

His father is a former baseball player and coach, and his mother is a full-time housewife. Once you get close to him, he shows a lot of his clumsy and somewhat foolish side.
