I've had this feeling while reading the Shino arc in Kanojo mo Kanojo. There's a sad, painful yet pleasant form of catharsis that readers get when a maiden in love silently backs down without making a fuss for everybody's sake while sacrificing their own happiness in the process. It's backwards and illogical, but I find this chapter quite fun to read and see it once again.
Catharsis done right is amazing. Most revenge porn in manga (especially in meh isekais and a popular one I won't name) makes my eye roll when they clumsily use it.
