Yandere Battle royale x Namjoon

I'm going to have both battle royales and Namjoon is Bi in this.

Namjoon Kim is the boyfriend of Shiori Kitano and she may not show much emotion but Namjoon knows she loves him like he does for her but what he doesn't know is that there were others in the school that liked him to even boys and they aren't happy your with Shiori but what happens when you are on you last day of school field trip when it takes a bit if a turn and now you have to kill each other but not just you another class to and there teacher is Shiori's father (I'm not gonna add the second teacher that just to much) but as this happens students from the other school fall for you as well.

Warning: I don't own anything and there will be sexual content and swearing if you don't like don't read
