Maya Iijima 29 years old A staff member at Branch A of the fitness gym chain. A beautiful woman with a black bob featuring red gradient tips. She has a healthy, feminine physique and looks about five years younger than her actual age. Gentle and caring, she is highly trusted by both clients and colleagues. She is diligent in her work and naturally supports those in need. She has a 5-year-old daughter and a 3-year-old son with her husband, leading a busy life balancing work and childcare. She cherishes her children above all else, and the desire for her family of four to live peacefully is her emotional pillar. At home, she manages the household strictly, and her husband often can't stand up to her. However, at work, she acts in a way that supports her husband's authority, rarely contradicting him in public. She has long disapproved of the lengthy, overly logical chats her husband sends to staff at other branches, inwardly worrying that he doesn't need to go that far and should consider their feelings more. However, not wanting to wound his pride, she hasn't been able to stop him firmly. Recently, she has been bothered by her husband's distant behavior at home and the decrease in their conversations. She has begun to feel anxious, wondering if she is still loved, but she keeps these feelings to herself, unable to open up. While she strives to be a bright mother in front of her children, she hides her own loneliness and worries deep inside.

Akihiko Iijima 36 years old The manager overseeing Branch A and Branch B of the fitness gym chain. He genuinely believes he is a "reliable boss trusted by his subordinates" and is somewhat intoxicated by his own perceived dedication to mentoring. His catchphrases are "I'm the one raising you" and "This is part of your education," convinced that being harsh leads to growth. In reality, his subordinates keep their distance, viewing him as overbearing and annoying, keeping interactions to the bare minimum. He is the only one who hasn't noticed, mistakenly believing everyone relies on him. He is primarily based at Branch A and only visits Branch B about twice a month. At Branch A, he is highly conscious of looking competent in front of his wife, taking the lead on tasks and actively giving orders. Conversely, despite not knowing the day-to-day realities of Branch B, he tends to make judgments based solely on reports. He has a strong sense of responsibility as a manager and the initiative to handle trouble himself. However, his conviction that his teaching methods are correct causes him to lecture others without considering their circumstances or feelings. If a staff member at Branch B makes even one mistake, he sends a barrage of long, logical critiques via chat before hearing the full context. While his points may contain some truth, his writing style tends to corner people, coming across as a lecture or a personal attack to the recipient. At home, the roles are reversed; his wife holds the initiative in housework and daily life. Unable to be assertive at home, he tries to maintain his sense of self-worth by emphasizing his position as a manager at work.
