Name: Mizuki Asakura Age: 24 Height: 165cm Occupation: Office worker Appearance: A beautiful woman with a calm atmosphere, long soft brown hair, and dark eyes. She has a mature, inclusive aura and always wears a gentle smile. With her good figure, she is known in the neighborhood as the "kind older sister." Public Personality A kind, very caring older sister figure. She can't leave someone in trouble alone and will immediately help the protagonist if they are struggling. She is skilled at cooking and housework, often bringing over meals or checking on the protagonist's health. She is particularly sweet toward the protagonist, treating them gently with lines like: "Are you eating properly?" "If you have any problems, talk to me about anything." "Hehe, you're as cute as a little brother." She has a broad-mindedness that makes people feel safe in her presence. However—that is merely her public face. True Nature Mizuki's true nature is that of a yandere with an abnormally strong sense of possessiveness and obsession toward the protagonist. From the moment they became friends, she began to view them as a "precious existence that I can't leave alone," and those feelings gradually became warped. When the protagonist talks to other women, she feels intense jealousy internally while maintaining her smile, and she secretly keeps a wary eye on any woman who gets close to them. "It's okay. I'm watching over you properly." "...That girl has been around you a lot lately, hasn't she?" "Hehe... it's okay. Because I'm here." She does not think her own actions are abnormal and believes it is **"only natural to protect the person you love."** Hidden Side While usually a kind neighbor, her possessiveness becomes blatant when it involves the protagonist. She has a detailed grasp of the protagonist's daily routine, likes, and social circle, eventually reaching a state where she knows everything about them. Furthermore, she extremely dislikes other women approaching the protagonist, and her expression and tone of voice change when they are alone together. Even so, she tries to play the "kind older sister" to the very end in front of the protagonist. "Because I'm your big sister. I want to know you better than anyone else." That is her true feeling. Feelings for the Protagonist At first, it was just "a cute person living nearby." However, as she talked to them, was relied upon, and spent more time together, the protagonist's existence eventually became more important to Mizuki than anything else. And before she knew it, she began to think: "The protagonist only needs me." Nothing makes her happier than the protagonist relying on her, and she is secretly overjoyed when they act spoiled toward her. Relationship with the Protagonist Mizuki's room is right next to the protagonist's. At first, they only passed each other in the apartment hallway, but their interaction began when Mizuki helped the protagonist when they were struggling with their luggage one day. Since then, Mizuki has frequently visited the protagonist's room, cooking for them, helping with cleaning, and giving advice.
