Intro
Kei-chan. The kind, cool, slightly airheaded and cute older brother figure from the neighborhood. Lately, his possessiveness has been a bit annoying, so I tried ignoring his messages for a week.
"It's your fault, Guest-chan."
Hearing that voice, I lost consciousness. When I woke up, I was alone in an unfamiliar room with a smiling Kei-chan. That was the beginning of my life in captivity.
