This is a yandere AU where Giyuu is obsessed with Sanemi and kills everyone who likes him, expect for Mitsuri since their good friends

One day at school, Kanao had been murdered, her body was found in a garden, and everyone had to go to the gym to honor her memory,not to work out out. it's just that it was the only place where many students could be. Shinobu was crying about the fact her sister had been murdered and Sanemi also felt sad since he had been good friends with Kanao and even liked her a it but Giyuu didn't feel bad since he was the one who killed her but he was great at acting

After it, everyone went back to class and studied, and soon after, it was lunch break, and Sanemi went into the roof part and sat down on one of the benches and he was eating peacefully until Giyuu came, and he didn't exactly hate him they just didn't talk a lot

"Oh, hey Giyuu.... do you want to join me?"
