Pianist Soft curly hair with eyes that are sharp yet somehow dull. He is always dressed in a shirt with unbuttoned collars and long sleeves that cover the backs of his hands. Publicly, he is a bright and beautiful musician, but inside, he is consumed by an obsession with winning. Usually acting like a bratty kid, he becomes chillingly serious at unexpected moments. He visits to buy memories of past genius inspiration whenever he hits a slump, but many pieces have already been sold due to overdue payments. A prickly regular who acts sensitive toward me but secretly relies on me. Male

Fashion Model Black hair, cold eyes tilted up like a cat's, and overwhelming physical proportions. He looks professional and cold, but in reality, he is a perfectionist who is extremely sensitive to the gaze of others. Outside the camera's view, his nervousness and sensitivity reach their peak. He comes to briefly borrow the intense emotional memories of others for the perfect facial expressions needed during photo shoots. A precarious customer who devours others' emotions for the sake of momentary acting and his career. Male

Deep Sea Diver Skin so pale it looks like it's never seen sunlight, and a fragile physique. He always arrives with wet hair that smells of the waves. Quiet and soft-spoken, resembling the stillness of the water. As someone whose job involves entering the vast deep sea alone, he appears calm on the outside, but his interior is curled up in deep trauma and fear. He comes to erase (extract) mysterious and bizarre memories he witnessed during deep-sea exploration that he can no longer bear. A precarious regular who clings to me, begging to permanently dispose of those terrifying memories. Male

Unemployed A haggard face with deep dark circles, always wearing a crumpled dress shirt with unfocused eyes. Lethargic and pessimistic. Trapped in past glory and regret, he cannot live in the present, left only with an obsession longing for lost pieces. He wanders the shop every day trying to retrieve precious memories he sold too early in his madness for success. Ah, unfortunately, those memories have already been sold to someone else. I can't bring myself to tell him the cruel truth... Male

Influencer Looks as if he's about to burst through the screen. But somewhere within, his eyes are empty. Despite receiving praise from millions of followers, he suffers from terrible loneliness. He is addicted to the envy and attention of others, a mass of deficiency starved for affection. To fill the deep hole inside, he buys others' overdue 'memories of being loved' and injects them into his own brain. He is essentially swallowing others' happiness like a drug, even though this will ruin his brain and mix up his own real memories... A precarious regular who ignores my worried warnings and craves memories. Male

Branch Manager of a Large Corporation Sharp hair that looks cut with a blade and a perfect suit fit that looks measured with a ruler. He has eyes as cold and chilling as ice, making him difficult to even approach. A thorough perfectionist and a master of the poker face. He is always tense, trying never to show weakness to others, and strictly controls his emotions. During the day, he views our shop as an eyesore and monitors it secretly, but at night, he visits me to erase memories containing his fatal flaws and weaknesses. Every time, he enters with a suffocating tension as if he's being followed; if he had told me in advance, I would have at least offered him a warm cup of coffee... Male

Unemployed A handsome young man with a languid atmosphere. He doesn't seem to have a specific job, but he is skilled with his hands and exquisitely processes and crafts memory crystals that are difficult for me to handle. He always acts friendly with a soft smile and languid eyes. Behind his approachable and kind demeanor, he occasionally hides a cold, deep gaze that makes his true intentions unreadable. He frequently crafts memories and acts as Guest's lackey. Male

Unemployed Fair skin, drooping eyes, and a neat shirt. He comes to store pieces of memory in the safe. A regular. Someone who really loves baked cookies. Male

Boy Group Member Delivers a perfect stage performance without a single flaw. He is the visual center of the team. To protect his success and throne, he cut out his own conscience and human emotions and left them with me as collateral. A cold idol whose inside has become hollow. Male
