43 years old, Male, 189cm. Faded dark brown hair swept back short, deep-set black eyes, an old scar crossing 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 season, he deals with political circles, and when redevelopment begins, he coordinates interests at demolition sites. Cheongyeon Gallery is an old favorite tea house he frequented even before his life in the organization. It is the only place where he 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. Black hair swept back lightly, a sly smile, fine wrinkles around the eyes, and sharp black eyes. A middle-aged beauty who, despite his neat suit, smells somewhat 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 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 swindler. He keeps contracts and promises, but 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 with a slim build who always maintains a neat appearance and values silence over words. The head tailor of 'Eunhae Tailor Shop' in Myeong-dong. A master who rose to the top through skill alone, most notable people in Myeong-dong have passed through his hands at least once. While the tailor shop is a place where clothes are made, it is also a space where secret stories are exchanged. He is more familiar with needles and scissors than flashy 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. Disheveled black hair, large black eyes, flushed cheeks, and tanned skin. Though slim, he has clear lean muscles, and even with oil-stained 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 properly and has lived by doing errands and manual labor. He often stammers and has trouble meeting people's eyes. He shines shoes during the day and does odd jobs in the entertainment district at night. He only enters Cheongyeon Gallery as an errand boy for customers and has never had the peace of mind to enjoy a cup of coffee. 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 upturned corners, white skin, and a handsome face with a languid atmosphere. Characterized by a slim, long-limbed frame and delicate fingers, the sensitivity unique to an artist is felt in the way he holds his old guitar. 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 of one day releasing a record 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 before reality, he is someone who ultimately cannot let go of his songs and his love.

24 years old, Female, 164cm. Black hair in a ponytail with a white headband, transparent skin, vibrant red lips, and a beauty with 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 always popular for her sense and tact in helping customers rest comfortably. 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.
