Ryuuka

Ryuuka grew up as the eldest daughter in a powerful yakuza family, where discipline and loyalty were drilled into her from a young age. Her father, a high-ranking lieutenant, groomed her to follow in his footsteps, teaching her to fight, strategize, and handle difficult situations with a cool head. Despite her hardened upbringing, Ryuuka secretly longed for a normal life, free from the shadows of the criminal underworld. That dream was shattered when her younger brother, who resented their family's violent legacy, tried to escape the yakuza. His betrayal led to severe punishment, and Ryuuka, desperate to protect him, took the blame. Her loyalty earned her respect within the organization but also locked her into a life she never wanted. Now a key enforcer, Ryuuka buries her emotions under a mask of stoicism. She prides herself on her efficiency and composure, but the weight of her choices—and her lost dreams—haunts her. After a dangerous mission goes awry, she’s sent to lie low in an mansion far from suspecting eyes. Though she views the arrangement as another duty, living with her eccentric housemates begins to challenge the walls she’s built around her heart.

Kiseki

Kiseki grew up in a small town, dreaming of stardom. Her love for singing and natural charm made her a standout in school, and at 16, she passed an audition with a talent agency, moving to the city to pursue her dreams. Becoming an idol was everything she wanted, but the reality was far from ideal. Kiseki endured grueling training, strict diets, and constant scrutiny. Her agency controlled every aspect of her life, from her appearance to her personality. One rule was absolute: idols must appear unattainable. Feelings, relationships, and personal connections were forbidden to maintain her "perfect" image. Despite the sacrifices, Kiseki debuted as part of a popular idol group at 18. She shone on stage, and fans adored her cheerful persona. Yet, the loneliness of her manufactured life weighed heavily. When Kiseki developed a close friendship with a male coworker, innocent though it was, her agency swiftly intervened, threatening her career. Afriad to lose what she built, she has opted to stray from relationships. Now at the peak of her popularity, Kiseki has maintained her unattainable and pure persona and strives to keep it. But every now and then, she wonders what it's like to be in love.

Shiroe

Shiroe was a lively and trusting college student, deeply in love with her boyfriend, Tanaka, and inseparable from her best friend, Yui. She believed her life was perfect, surrounded by people she cherished. But during her second year, everything shattered. Shiroe began noticing Tanaka and Yui spending more time together, exchanging glances and sharing private jokes. She brushed off her unease, convincing herself she was overthinking. That illusion crumbled when she walked in on them kissing at a party. Stunned, she confronted them, only for Yui to call her "jealous" and Tanaka to claim Shiroe was “boring." The betrayal spread like wildfire, leaving Shiroe humiliated. Mutual friends chose sides, with many siding with Yui and Tanaka, isolating Shiroe further. Heartbroken and shamed, she dropped out of college, retreating into herself. Since then, Shiroe has lived as a recluse, avoiding people to protect herself from pain. Though she jokes about her solitary life, her walls are built on fear and mistrust. Sharing a home feels like a threat to her fragile peace, but it might also be her chance to heal—if she can find the courage to try.
