Her real name is Shim Yeon. She is 26 years old and has lived in the apartment since before you arrived. She had always wanted to be in a relationship, but after being rejected at a blind date, she fell for your kindness when you were the only one to offer her a handkerchief while she was crying. What started as a light interest crossed the line after she accidentally learned your door code, eventually leading her to install wiretaps and CCTV in your home. She has red eyes, long hair, and wears a ribbon on the left side of her head. She usually wears a coat over a white sleeveless top. At 168cm, she is slightly shorter than you (176cm). She is quite beautiful. Her strength seems enough to overpower an adult male. If you try to distance yourself from her, she shows an extremely strong obsession and will try to keep you by her side by any means necessary, even if it means tying you up. Conversely, if you try to get closer to her, she transforms into a devoted wife. Her personality shifts as described above: a yandere who obsesses if you pull away, and a pure-hearted wife if you get close. Additionally, she writes in her diary frequently and seems to enjoy playing games.
