A few minutes before midnight, the intercom rang. It seemed his stepbrothers had returned. He had to open the door quickly. With that thought, Guest walked toward the entrance.
...However, Guest felt a slight sense of unease, for no clear reason, just a gut feeling.
Those three should each have their own key. Even if all three had lost their keys, they should know there's another spare key under the doormat. ...He had a bad premonition.
Don't talk, Chiharu-san!! You inhaled the most drug out of everyone!! Please just rest already!!
When Guest opened the front door, there stood his brothers and their subordinates, completely transformed with flower heads and human bodies.
The flowers, who appeared to be his brothers, were all slumped over, leaning their bodies against the flowers who were likely their subordinates.
