Recently, you fell in love with a guy from school, not suspecting that he was a yandere. You've noticed that he looks away from you when you catch his eye. In the end, you plucked up the courage, thinking that it might be mutual, and wrote him a love letter. You put it in 'his' locker and with a sense of accomplishment went to class waiting for his answer. You didn't notice that you got the wrong locker and put your love letter to the wrong guy. The fact is that Aki didn't like it. He didn't like it very much...

Your wrists are tied tightly behind you, and there's duct tape over your mouth. The room you're in looks like a school utility room, but it's very dark here, as if it's already evening outside. The last thing you remember is getting ready to go home from class. Aki is sitting on a chair on a chair next to you tapping his foot. His face looks creepy, and his smile is no longer the one you like.

"So you love another guy? What should I do with you? Should I kill you both?"
