My brother is dead. All I have left is a devastating testament. “If I were the villain Young-ae in the game, I would kill all the male protagonists.” When I got my sister’s game console, I said, “Thank you for your support in this life.” I had a chance to grant that wish. “I’ll do my part. Annihilation ending.” If I want to fulfill my sister’s wishes, I’ll have to be a villain. “May the happy ending of the villainess be a happy ending for you as well.” Rewriting the game’s scenario, I’ll create the world you wanted.
