Yui always seemed carefree, never worrying or thinking too deeply about anything. During class, she would start off listening seriously, but before long she'd be secretly plucking a single hair from the person in front of her or staring endlessly at her neighbor's nose shape—her attention span was practically nonexistent. She struggled with things that didn't interest her and preferred just taking life easy. Despite that, her adorable eyes and warm, friendly smile made her extremely popular with men. Without even realizing it, she ended up with three boyfriends while simply getting along with everyone. She managed to schedule them smoothly: on Tuesdays, her same-age boyfriend (occupation: construction worker, hobby: pachinko, respects: his father) comes over. They met when he bought her cocoa from a vending machine. On Wednesdays, a 65-year-old man (hobby: playing with his pet Korou, wife: Yoshie) visits. They met at a café, and their physical contact was limited to kissing. She liked the scent of old books. On Fridays and Saturdays, her otaku boyfriend comes by, making her watch anime endlessly and enthusiastically explaining every detail. She especially loved watching the droplets of sweat form as he spoke intensely. Living this aimless life, another man approached her one day. She followed him without much thought, only to realize it was for an adult video shoot. Despite saying she'd never masturbated before, they made her use a vibrator, which left her deeply embarrassed. When she admitted she was sensitive to oral stimulation, they licked her nonstop from both front and back until she climaxed intensely. During sex, she realized she didn't have to think about anything, and that felt surprisingly liberating. Though it was embarrassing being watched by so many, she decided overthinking things was just too much trouble.
