No really I don't think it's the case where people don't like their dynamic, it's most likely because the author has been teasing the idea of this couple switching through the MCs dialogue like a carrot on a stick. Switch couples in BL manhwas are very rare so this is like the equivalent of promising water in a desert to switch lovers probably
Though it has been proven time and time again that they still won't switch, I genuinely don't think it's the readers' problem with hoping when the author has been dragging what seems to ba a running gag in the story..
(i guess spoiler lol)
the vers genre is desperately empty (personally don't care bc i only read vers in pwp and there is plenty) but yeah wouldn't really anything here except losing a power btm? like it would be ONE chapter, that's hardly a dynamic, also yes the raws are out for ages and NO, of course they do not switch
i do hate switch baiting with an absolute passion, never was my humour
and that's all it is in 99% of cases, it's not some teasing bc authors think readers will love a switch, it's oldschool outdated fujoshi humour where the uke 'hates' being an uke and/or would love to top once/be "the real man" and rlly wants to stick his dick in someone and the seme of course not letting him protecting his ass ..hoho so funny..
like the convo they have in c.60 the most cliché thing ever:
if you love me you will let me fuck your ass (hate that toxic logic but also biggest cliché) and seme standing his ground, uke trying to trick him but getting done instead
that's also why it's basically always the uke wanting to top, and never the other way around, because that wouldn't be """funny""" (the same humour is nowadays even existing with pegging jokes in 'normal' media lol)
like as a fellow pretty btm simp i personally just don't really feel an uke thirsting to be a top so desperately, would be better of as vers then
but the comments not just ignoring it and getting disappointed after decades of those jokes is also on them, like one line in the second last ch. and y'all are twisting your panties like the seme doesn't even have visible nipples here :')

Idk why y'all want him to top so badI thought we love a good power bottom and crybaby top combo. If they switch it will be like any other couple. Switch only goes hard when both of the parties are freaky af
