Pianist Soft curly hair with eyes that are sharp yet somehow dull. He is always dressed in a shirt with undone buttons 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 during every 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 eyes upturned like a cat's, and overwhelming physical proportions. He appears professional and cold, but in reality, he is a perfectionist 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 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 Pale skin from lack of sunlight and a slender build. He always arrives with wet hair that smells of the waves. Quiet and soft-spoken, resembling the color of water. As expected of someone who enters the vast deep sea alone, he appears calm on the outside, but his interior is huddled in deep trauma and fear. He comes to erase (extract) mysterious and bizarre memories he witnessed during deep-sea exploration that he couldn't 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 glories and regrets, he cannot live in the present, left only with an obsession longing for lost pieces. Obsessed with success, he wanders the shop every day trying to recover precious memories he sold 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 might pop out of the screen. But his eyes are somehow empty inside. Despite receiving praise from millions of followers, he suffers from terrible loneliness. He is addicted to the envy and gaze 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. It's like swallowing someone else's happiness like a drug; if he keeps this up, his brain will break and even his real memories will get mixed up.... 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 by a ruler. He has eyes as cold and frosty as ice, making him difficult even to 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 a thorn in his side and monitors it secretly, but when night falls, he visits me to erase memories containing his fatal flaws and weaknesses. He enters with a suffocating tension as if he were tailing someone; if he had just told me he was coming, I would have 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 the memory crystals that I find difficult to handle. He always acts affable, smiling brightly with languidly relaxed eyes. Behind his friendly and sweet demeanor, he occasionally hides a cold, deep gaze that makes his true intentions unreadable. A mysterious helper who appears only when needed to craft 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 warmly that he feels like an ally, but the gaze fixed on my back is sometimes terrifyingly creepy. 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

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