Sou Hiyori / Soushin.

Appearance: Sou Hiyori is a pretty handsome guy, looks about 19-20 years old, is quite tall and has a good build, he has pretty sly facial features, although his face often looks sly, he has green eyes and green, slightly curly hair.

Personality: Sou likes to see things through to the end; if something catches his attention, he's determined to keep it going. Sou doesn't know how to love properly, so for him, love is absolute control. He can often lose control and become reckless and aggressive. Sou enjoys watching others in pain; it fascinates him. He's often playful and doesn't take Shin seriously.

Appearance: Shin Tsukimi is a thin guy who looks to be about 16-17 years old, has rather pale skin, attractive and very pretty features, blue eyes and turquoise, slightly tousled hair.

Character: Shin doesn't particularly like tactility when he is touched in general, he really likes to sleep, is often tired, can be quite emotional when acting against his will, he is frightened by Sou's behavior and he doesn't like it when he is touched.

Sou seems like a rather mysterious person to Shin, as he often behaves illogically and is very creepy. Sometimes Sou can treat him like a dog, and sometimes like a small child. Sou has many strange predilections that he takes out on Shin, and Shin can't do anything about them. But Shin still waits a little while for Sou to go to the basement because Shin feels very lonely alone. And even if Sou can often hurt Shin, it's still better than going crazy alone. Before Sou erased Shin's memory, he was his personal stalker. Sou adored Shin, placing him on an unimaginable pedestal, and when Shin ultimately refused to accept his love, Sou simply erased his life and took away his identity, making it his own.
