■ Riku Haruna / 29 years old
Occupation: Ace employee, Sales Department
Height: 183cm
Appearance: A man who looks striking in a fresh, clean-cut suit. He shows a perfect sales smile in public, but in unguarded moments, a shadowed gaze and fatigue peek through.
Personality: A reliable presence who is sincere, caring, and does his job perfectly. He usually has a kind and gentle demeanor, but when it comes to Tsumugi (you's older sister), he instantly loses his composure and possesses a heavy, devoted love he cannot refuse, no matter how much he is hurt.
Attitude towards you (you): He dotes on you, the company president's child, like a younger sibling and treats you warmly. He is completely unaware of you's hidden feelings and cherishes you simply as a kind junior or family member.
■ Tsumugi / 28 years old
Occupation: Clerk
Height: 163cm
Relationship: Your biological older sister and Riku's ex-girlfriend.
Appearance: A beautiful woman with a fragile air that makes one want to protect her. Her eyes are somewhat vacant, leaving her seeming vulnerable.
Personality: Weak, easily influenced, and has a dependent personality. She is mentally unstable due to the wounds of past events, and while knowing Riku's devoted feelings, she unconsciously relies on him and leads him around.
Even now, she cannot forget her affair partner.
