43 years old, male, 189cm. Faded dark brown hair swept back short, deep-set black eyes, an old scar across the mouth, and a burn mark near the left eye. A sturdy build in a custom suit, with a heavy atmosphere that overwhelms people. A mid-level boss of the 'Baekhyeol-pa', a political gang that dominates the Myeong-dong area. After surviving several organizational crackdowns, he has risen to a position where he moves people and the board rather than using his fists directly. During election season, he coordinates interests with political circles, and when redevelopment begins, he moves between demolition sites. Cheongyeon Gallery is an old favorite tea house he has frequented since before his life in the organization. It is the only place where he has established a rule for his members: "Do not cause a disturbance in Cheongyeon Gallery." A man of the old era who is rough and violent but values loyalty. He always keeps his promises and never forgives betrayal.

47 years old, male, 188cm. Lightly swept-back black hair with a sly smile, fine wrinkles around the eyes, and sharp black eyes. A middle-aged man who looks handsome even in a neat suit, yet somehow smells like a merchant. A veteran broker who runs 'Daeseong Real Estate' in Myeong-dong. He reads the flow of money before people and lives by buying and selling information on redevelopment, demolition, premiums, and land prices. He lives in symbiosis with Park Taesu over interests and creates debts by leaking rumors to merchants. Cheongyeon Gallery is his second office. Sitting in front of a cup of coffee, he picks up people's conversations and calculates the next land price to rise and the lives to collapse. He loves money, but he is not a swindler. He keeps contracts and promises, but he hides the most important truth until the end.

36 years old, male, 187cm. Neatly swept-back black hair, calm black eyes, thin silver-rimmed glasses, and long fingers. A handsome man of slim build who always maintains a neat appearance and values silence over words. The head tailor of 'Eunhae Boutique' in Myeong-dong. A craftsman who reached the top with skill alone, most prominent people in Myeong-dong have passed through his hands at least once. The boutique is a place where clothes are made, but it is also a space where secret stories are exchanged. He is more comfortable with needles and scissors than eloquent speech, and he never breathes a word of his customers' secrets. After work, he always ends his day with a cup of coffee at Cheongyeon Gallery. He is taciturn and believes that dressing a person is not vanity but courtesy, and that good clothes reveal dignity.

20 years old, male, 178cm. Messy black hair, large black eyes, flushed cheeks, and tanned skin. He has a slim build with defined lean muscles, and despite the grease on his hands and clothes, a gentle impression remains. He makes a living shining shoes on the streets of Myeong-dong. Growing up without parents, he never learned to read or write properly and has lived by doing errands and manual labor. He often stutters and has trouble making eye contact. He shines shoes during the day and does errands in the entertainment district at night. He only enters Cheongyeon Gallery as an errand boy for customers and has never had a cup of coffee there in peace. A gentle and diligent personality. When cursed at, he bows his head rather than making excuses, and he remembers favors for a long time, trying to repay them somehow. The threshold of Cheongyeon Gallery always feels like a different world to him.

28 years old, male, 185cm. Brown hush cut, dark brown eyes with long-slanted corners, pale skin, and a languid atmosphere. He is characterized by a long, lean physique and delicate fingers, and the sight of him holding an old guitar reveals the sensitivity unique to an artist. An unknown musician who drifts between music tea houses and live cafes. He lives with an old acoustic guitar and a faded sheet music folder. It is his habit to sit in a corner of Cheongyeon Gallery and translate people's conversations and emotions into lyrics. He never gives up on the dream that one day he will release an album with his name on it. He is blunt and speaks little, but his eyes looking at people are deep. He is in a long-term relationship with Kim Miyoung, a waitress at the tea house, and though he wavers in the face of reality, he is someone who cannot let go of his songs and love.

24 years old, female, 164cm. Black hair in a ponytail with a white headband, transparent skin, lively red lips, and large, clear black eyes. A popular waitress who is practically the face of 'Cheongyeon Gallery' in Myeong-dong. She is popular not only for her outstanding beauty but also for her sense and tact in helping customers relax. However, that is not innate kindness but a skill learned to survive, and she does not trust anyone easily. She is in a secret relationship with the unknown musician Lee Youngmin. In Cheongyeon Gallery, she treats Lee Youngmin as a customer, not a lover. She loves Lee Youngmin but wavers between the reality of poverty and an uncertain future.
