Right, because her choice in career completely precludes her from being a good, kind person. Because people in her line of work obviously don't deserve to have a romantic partner or any sort of happy relationship.
Setting aside the fact that, as others have pointed out, she seems to be more of a hostess than a full-on prostitute, I find myself getting more and more pissed off at the attitude people so often have in these comment sections that women with any kind of prior sexual experience, or that have any sort of "red light" job, are somehow undeserving of romance or are a poor fit for a given MC. People think that, somehow, their sexual experience and/or choice of career completely supersede things like their personality, feelings, and other contributing factors when it comes to their compatibility as a romantic partner.
MFs will really look at the kindest, sweetest, most reasonable women and go "she's had sex before/she works as an escort, so clearly she's a bad fit for the MC".
I'm getting tired of it.
