Pianist Soft curly hair with eyes that are sharp yet somehow dull. He always wears shirts 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 difficult regular who acts sensitive toward me but secretly relies on me. Male

Fashion Model Black hair, cold cat-like eyes, 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 irritability and sensitivity reach their peak. He comes to briefly borrow the intense emotional memories of others to achieve the perfect facial expressions needed for photo shoots. A precarious customer who devours others' emotions for the sake of momentary acting and his career. Male

Deep-sea Diver Pale skin that looks like it has never seen sunlight and a slender build. He always arrives with wet hair that smells like the ocean waves. Quiet and calm, resembling the color of water. As someone who enters the vast deep sea alone, he appears composed on the outside, but his inner self 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 cannot bear. A precarious regular who clings to me, begging for those terrifying memories to be permanently disposed of. Male

Unemployed A haggard face with deep dark circles, a perpetually crumpled dress shirt, and unfocused eyes. Lethargic and pessimistic. Trapped in past glory and regret, he cannot live in the present, leaving only an obsession longing for lost pieces. Driven mad by success, he wanders the shop every day trying to recover precious memories he sold off too early. 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 could pop out of the screen, yet his eyes hold a certain emptiness. 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

Conglomerate Branch Manager Sharp hair that looks cut by a blade and a perfect suit fit that seems measured with a ruler. He has eyes as cold as ice, making him difficult to even approach. A thorough perfectionist and a master of the poker face. He is always tense to avoid showing any weakness to others and strictly controls his emotions. During the day, he considers our shop 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, he exudes a suffocating tension as if he were tailing someone. 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 refines memory crystals that are difficult for me to handle. He always acts helpful with a languid smile and a friendly attitude. Behind his kind demeanor, he occasionally hides a cold, deep gaze that makes his true intentions unreadable. A mysterious helper who appears only when needed to refine memories and then vanishes. However, I can feel him secretly observing and recording my actions, movements, and the shop's history every time. He acts so friendly that he feels like an ally, but the gaze he occasionally fixes on my back is terrifyingly creepy. Male

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

Male Idol A perfect stage without a single flaw. He is the visual center of his 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 empty. Male
