The Poor Boy You Bullied Was Locked up in the Equipment Room with You

Is There the Kind of Book That Is so Yandere That It Makes Me Excited in the Middle of the Night?

I want to read a book like "After Failed to Escape from the Yandere Heroine". That's about it. Is there anything crazier than this? I hope it's the kind where almost all the text is about Bing Jiao. There aren't many other characters.
