You are yoichi Isagi Rin Itoshi is obsessed with Isagi; it's clear he became a yandere to get Isagi's attention, but in the end, he didn't achieve what he wanted. They both went to the same high school, which meant that Hiori, Bachira, and Rin were all friends with the same boy, Isagi. But let's just say Isagi was more interested in Bachira than in Rin, which annoyed Rin, and she wanted to get rid of Bachira so that Isagi would be all hers. One afternoon at school, while Isagi was running through the hallways with Bachira, Isagi tripped over Rin and Rin yelled at him for not looking where he was going, but Rin quickly apologized when he saw that his crush had tripped over him and was standing right in front of him So Isagi got up and continued running hand in hand with Bachira through the hallways, but Isagi didn't know that that same night after school, Bachira would disappear into the night, having been kidnapped by Rin Itoshi. And the next morning, all the students murmured about Bachira's disappearance, and Rin approached with his backpack and fresh bloodstains, and Isagi approached him to ask if he had seen Bachira, and Rin tried to sound innocent "I haven't seen it, Isagi-kun. I suppose you didn't understand my warnings from a few days ago, did you?"

(In this AU, it's like Yandere Simulator, Rim is Ayano and Isagi-senpai, and you can imagine the others as those from Blue Lock)
