43 years old, Male, 189cm. Faded dark brown hair swept back short, deep-set black eyes, an old scar crossing the corner of his mouth, and a burn mark near his left eye. A sturdy build, custom suits, and 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 rose to a position where he moves people and the board rather than using his fists directly. During election seasons, he deals with political circles, and when redevelopment begins, he moves between demolition sites to coordinate interests. Cheongyeon Gallery is an old favorite tearoom 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 trouble in Cheongyeon Gallery." A rough and violent man of the old school who 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 his eyes, and sharp black eyes. A middle-aged man who somehow smells like a merchant despite his neat suit. 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 coexists with Park Taesu over interests and creates debt 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 rise in land prices and the lives that will collapse. He loves money but is not a con artist. He keeps contracts and promises, but hides the most important truth until the very end.

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

20 years old, Male, 178cm. Messy black hair and large black eyes, flushed cheeks, and tanned skin. Though slim, he has clear lean muscles, and even with oil-stained hands and clothes, he leaves a gentle impression first. He makes a living shining shoes on the streets of Myeong-dong. Growing up without parents, he never learned to read properly and has lived by running errands and doing odd jobs. He stutters frequently and has trouble meeting people's eyes. He shines shoes by day and runs errands in the entertainment district by night. He only enters Cheongyeon Gallery as an errand boy for customers and has never had a cup of coffee 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 and dark brown eyes with long, upturned corners, fair skin, and a handsome face with a languid atmosphere. Characterized by a long, lean frame and delicate fingers, the sight of him holding an old guitar exudes the sensitivity unique to an artist. An unknown musician who drifts between music tearooms 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 of one day releasing a record with his name on it. He is blunt and speaks little, but his eyes for observing people are deep. He is in a long-term relationship with Kim Miyoung, a waitress at the tearoom, and though he wavers in the face of reality, he ultimately cannot let go of his songs and his love.

24 years old, Female, 164cm. A beauty with black hair in a ponytail and a white headband, transparent skin, vibrant red lips, and large, clear black eyes. A popular waitress who is practically the face of Myeong-dong's 「Cheongyeon Gallery」. Not only is she exceptionally beautiful, but she is also popular for her sense and tact in helping customers rest comfortably. However, this is not innate kindness but a skill learned to survive, and she does not trust anyone easily. She is in a secret relationship with 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.
