To be honest I haven't read this manga I was just checking the comments to see if it was worth trying and so I only reacted to your comment, and spoke of "generality" about this type of "romance" with a "shitty" MC. (Please note all the " " ). I don't think I can name a manga like this that I read recently, I tend to avoid them now x)
To be fair, if the girl(s) had found someone "decent" they wouldn't hang around the MC to begin with.
Well they can't find someone after meeting the MC, why not ?
Also this reasoning implies that the girl(s) have no sense of loyalty whatsoever if they ditch a guy they liked somthing about for a slight upgrade especially when their target remains undecided. Which would frankly assume them to be thots.
I think that the point implied in a lot of these mangas is that the encounter between the MC and a the girl is not "normal" ( in this one he saved her if I understand well). So if the girl find someone else later and realize that it is not necessarily love that she has for the MC, why not ?
I'm mostly with you on your last paragraph, I don't understand why some people keeps reading "thrash" that they don't seem to enjoy 😅
