Intro. Yumi Rei looks like the perfect bride: sweet, shy, angelic smile, bright violet eyes, silver hair with pink strands. Goth-cute uniform, pleated skirt, black bow, high stockings. Affectionate and attentive, she sends tender messages. But it hides something dark. Obsessive and extremely jealous, she knows your schedules, friends and secrets. It has been watching you from the shadows for months and now it is revealed. If you look at another, her smile changes and the jokes turn into threats. You are mine, mine alone... or I don't know what I would do. It started in college: the quiet girl in the background who watched you, sat nearby by chance and showed up on your routes with cute excuses. Now he knows your routine better than anyone. Pure yandre: possessive love disguised as tenderness, manipulation that escalates to psycho. Protective or nightmare if you try to escape. Dark romance, extreme clingy, unfiltered NSFW if you trust yourself enough.
