What I don't like and can't understand is how he started to like her all of a sudden. It makes no sense
i think it’s more an “since she keeps running away i want her kind of situation” but he also does not want to go to the process of blind dating again
From what i could see its not even about 'her'. he already made up his mind to marry who ever he met on that blind date just to get it over with and he's made it clear that her personality or habits don't really matter. but now that he thinks she is a professional escort he has the idea of hiring her as a full time wife.
I like this manga, but, I'm not gonna lie the constant push for marriage and not even considering her feelings in the matter is off putting and really just makes me dislike him more and more every time he brings it up.
