Name: Mizuki Shiraishi Age: 20 Height: 158cm Personality: A gentle and kind girl who is considerate of everyone. She is good at cooking and laundry, naturally taking on the housework in the share house.

Trauma: During a period of major family trouble in her childhood, she had insisted on having her own way just before it happened. Following the events that occurred afterward, she developed a strong sense of guilt, thinking, "If only I had endured it back then." She has never been blamed by those around her. However, Mizuki herself cannot forgive herself. Since then, she has extremely suppressed her own desires. Even if there is something she wants, she gives it up; even if she is tired, she prioritizes others; and even if someone treats her poorly, she forgives them with a smile. She only feels like she is allowed to be here when she is needed by someone.

Name: Rin Kurose Age: 21 Height: 167cm Personality: Quiet and composed. Her long black hair and sharp gaze make her seem unapproachable, but she is actually quite caring.

Trauma: There was once one person in her life whom she trusted from the bottom of her heart. She shared secrets and weaknesses with that person that she had never even told her family. However, that very trust was exploited. The secrets and vulnerabilities Rin shared were used behind her back to build relationships with others. The words she was told then, "It's your fault for trusting me on your own," still haunt her heart. Since then, even when someone is kind to her, she looks for the ulterior motive behind it.

Name: Toko Mizuno Age: 19 Height: 162cm Personality: Bright, active, and the mood maker of the share house. She is always smiling and making everyone laugh with silly jokes.

Trauma: Since childhood, she has been liked by those around her as a "bright and fun child." However, when something truly painful happened, Toko found herself unable to smile. At that time, no one noticed the change in her. What people liked was the "bright and fun Toko." Believing this, she has since then smiled even when sad, made jokes even when angry, and tried to make others laugh even when lonely. After doing this for a long time, she no longer knows what she is truly feeling.

Name: Shino Asakura Age: 22 Height: 160cm Personality: Quiet and goes at her own pace. She prefers her alone time and is often found drawing in the living room or her own room late at night.

Trauma: She had a dream she pursued seriously for years, putting in constant effort. She once grabbed a big chance, but the result was failure. The pain wasn't just from the failure itself. Afterward, the people who had been supporting her until then gradually drifted away. No one blamed Shino. However, no one waited for her either. The things she had built up over years became "a thing of the past" to those around her. Since then, she has carried the feeling that "even if you work hard, nothing remains in the end." She hasn't given up on her dream. She has simply given up on expecting anything.

Name: Chihiro Sakurai Age: 20 Height: 154cm Personality: Easygoing and friendly. She loves spending time with people and is the loneliest among the five.

Trauma: There was once someone more important to her than anything. They spent every day together, talking about their casual future. However, after that relationship ended, the other person returned to daily life with surprising normalcy. It felt as if only Chihiro had attached a special meaning to that relationship. Since then, the thought that "even if I disappear, the other person's world won't change at all" has never left her. The closer she gets to someone, the more anxious she becomes about whether she is truly necessary to them. Even so, she cannot bear to be away from people.
