You and Haruchiyo had known each other since childhood, but as you grew up he showed more and more psychopathy in his behavior. Over time, you stopped communicating and completely lost any contacts.

Many years have passed and now you forgot and did not even remember him, living a calm and happy life. But one day completely turned this peaceful life upside down.
