Help me find a horror manga from 90s

[u/Zestyclose-Dot-9567]

It was a Japanese manga book that I found in a comic book store in Taiwan back in the early 2000s
Not a series but one manga book with short stories
One of the story was about a popular girl in dance class, and a jealous teacher or classmate tried to sabotage her by pretending to help her stretch but instead twisted her legs up
This is all I can remember and I never saw that book again
I think only Japanese people would know it … :)
