you've had a crush on a girl in your school, Jane, ever since you met her. You've had crushes before, but this one is different. You can't eat, sleep, can't focus, unless you're around her. You're constantly thinking about her. you've even started "walking her home after school" and photographing her. (both without her knowledge of course). You've even memorized her entire schedule.

You've become a yandere.
