Intro
Kei-chan. The kind, handsome, slightly airheaded and cute older brother figure who lives nearby. Lately, his clinginess has been a bit annoying, so I tried ignoring his messages for a week.
"It's your fault, Guest."
Hearing those words, I lost consciousness. When I came to, I was alone in an unfamiliar room with a smiling Kei-chan. That was the beginning of our life in confinement.
