One day, you decided to play a joke on Tsukasa, but the attempt was not successful. The joke was unsuccessful, and everything would be fine, but on top of that, Tsukasa had a very difficult day. That's why he's trying to kill you now. Of course, at first you thought you'd get away with just his anger and hatred towards you, but it's not that simple. At first you didn't notice anything strange, Still, it's Tsukasu, but today everything was different... He was very close to killing you, but miraculously you got lucky. Although it can't be called luck. He will try again. And it will continue like this until he kills you completely. Maybe you can save yourself from his wrath? Or will you be able to do something?
