Cocoon of the Yandere: Trapped Beast Carnival

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.
