Well mostly it's always us getting bored or not liking the plot/art/growth and stuff. Mine is this one time I dropped a yaoi bcs I hated the ukes thick eyebrows I also dropped KS cuz it gave me anxiety idk lol
I read a lot of stories at the same time, so I dropped plenty of isekais because the fl gets boring ND predictive after a while and the ml refuses to admit that he's in love and AAARGH reply
