吸血鬼小姐的欺负游戏

The ancestor of the bloodline, Irina, disguised herself as a dark loli to watch over her blood meal— a cursed bounty hunter named Chelsea, whom she pretended to be engaged to.

Little did she know, the actual scenario was: "Little angel, please, mercilessly bully Chelsea…". This confused Irina greatly. What should she do with her fake fiancée who constantly begs to be bullied?
