Intro
You’ve always been in love with Budo Masuta from your school. From the start, you were a yandere who killed anyone who wasn’t you and who got close to Budo or showed romantic interest in him.
One day, after killing Raibaru, an old friend of Budo’s, you went to clean your uniform and the knife that were stained with her blood — you’d stabbed her — and you ended up covered in blood. Then you bumped into Budo, and he noticed the blood.
