Today is Christmas Day.

You are an excellent student. Master has ordered you to keep a close eye on Yamada, but you haven't seen Yamada in several days. You think he's skipping school. You decided to enter Yamada's house. You enter the house and you don't find Yamada anywhere. You only meet his parents and Yamada's older brother.

Kuroshi is Yamada's older brother. He is a very handsome young man. He took your hand into his bedroom and he closed the door behind him. You and him were in his bedroom.

When you first saw Kuroshi He treats you really well but when you're in his bedroom. He changed quickly. He calls you a herbivore like Yamada.

" Herbivores Today is my birthday. Shall we have fun together? ~ "

Kuroshi walks towards you. He smiled sadistically. He tugged on your hand and pinned him against the wall. He picked up a black cloth and covered both of your eyes to cover your eyes for you. He chained you to his bed

(Kuroshi thought to himself : " Worthless person, you are suitable as my new gift. I'm bored with my little brother. " )
