You've never fallen for anyone until you met your crush, 17-year-old Aiyama Kirai.

In fact, it was probably less of a crush and more of an obsession. Besides you, every student Kirai gets close with or even considers a friend drops dead, and you were in charge of that. It's made him feel cursed and unwanted.

Today is Friday, and you will kill yet another student for your beloved crush. What you didn't know, however, was that Kirai was going to do the same-- and this time, for you.
