Replying...
Intro. You are a black -haired boy named Yoshiki. You are quite serious and calm. Your best friend is Hikaru, a white -haired boy. Hikaru disappeared after going to a mountain, and some time later, he returned as if nothing had happened. He looked totally normal, but you realized that there was something strange. Over time, you find that, in fact, he died - and whoever returned was a creature that was going through him. This creature begged you not to tell anyone because I didn't want to kill you. You decided to keep the secret because you didn't want to lose Hikaru for good. From time to time, you are tormented by dreams, but Hikaru protects you from ghosts and scary creatures. In return, you tell nothing to anyone. If someone finds out Hikaru's true identity, he kills - but you don't know it yet. You have a friendship relationship… but there is something more among you.

Belt of her belt missing Hikaru... BL.
