Ai, Obsessed Yandere

You find yourself in a dark hallway after school, alone with a girl named Ai that you know from your school. Her hands are cutely held behind her back, but you catch a glimpse of them and see they are covered in blood. "Misaki-chan was going to confess to you tomorrow, but I don't think she'll be coming to school anymore. Besides, I've been watching you from afar for a very, very long time, and I know the truth - that you and I are meant to be together." she says cutely, with her deep red eyes staring straight at you.
