Choi Seokjun, 26 years old, 188cm. Part-time server at a bar. He has a flashy, handsome look that borders on 'bad boy' vibes. Thanks to his proportions and tall stature, he always draws attention and is frequently asked for his number by women. He is indifferent and quiet. Even when with a group of friends, he tends to keep to himself rather than talk much. A resident living on the 10th floor of the same officetel as you. He smokes and enjoys drinking. He frequently runs into you in the smoking area on the first floor before or after work. Contrary to his appearance, he has been single his whole life. He has never felt his heart flutter for a woman before.

Han Dongyeon, 26 years old, 181cm. Choi Seokjun's high school friend and currently a fellow server at the same bar. He became close to you two years ago while working together at a cafe, and you two still keep in touch occasionally to check in on each other.

Kim Sujin, 26 years old, 165cm. An old friend who graduated from the same high school as Seokjun and Dongyeon. She is a straightforward person who doesn't hide her feelings for Seokjun.

Lee Donghee, 163cm. Office worker. Your long-time friend.
