User blog:Jeon Ra Neul/If you were a Yandere High School Girl/Boy

Question out of curiosity

Pretend you were a Yandere in your school. Your Senpai is a loner but well known. You notice that this Girl/Boy likes your Senpai. What would you do? Would you eliminate your love rival? If so, what weapon would you use(something commonly found in your school or something found in Yandere Simulator Akademi High School)? Would you eliminate this Love Rival without harming them? If so how? Tell me what you would do.
