Lmao the yuri ending happened once in a genderswap manga and you feel tired. You know how tired I get of the het-slop defaultism? I wanted to maim the person who wrote Blue Flag, no spoilers but ughhhh. Anyways, drop the link?
Same, it feels to me like 1 in 5 genderswap mangas have a yuri ending and it's usually very signposted long before then so I have no idea why people complain when they encounter it.
Incidentally, while I personally don't have an issue with het endings the problem with them is how lazy comphet chemistry is. The notion of "put a boy and girl together long enough and they'll fall in love" is such horseshit and so many writers fall back on that to get around having to give the characters chemistry. Or in the absolute worst cases, skipping out on developing the obvious audience surrogate character completely.
(not that I haven't read bad/lazy yuri works, but at least two girls holding hands or kissing is pretty visually appealing to me even when the story is a wash)
