Sorry, should've said that as "I don't like it when their personality is not like what I want in the first place and they don't change that to what I want" instead.
And yes, nothing wrong with that. Anyway, in case you forget, their relationship is still not 3 years, yet.
Of course there is nothing wrong with that, some people want couples to evolve, especially in the Manga space where wholesome stories are either ending when they start dating, or are super ultra shy hihi, touching is disgusting...
So again, you're missing the point. It is not about not liking the status quo. It is about not looking at the status quo for 170 chapters.
Many love this snails pace, others won't. And it's not like the author of this story told the people hoping for more, that it will never come. So what exactly do you expect these people to do, but hope for the best with the premise, story and/or characters they enjoy?
"You don't like it, don't read it", is kinda played out at this point and just not realistic. Because most people disappointed here, are not here because they "didn't like it", it's because they enjoyed it and wanted more out of it. That's all really.
Of course pure haters will always exist, but I didn't see seething hate too much here yet.
A big clap for translators, big clap for authors and a big clap for ourselves for sticking this long....
