Why this got low rating??

I would have preferred if fl had been the original. The misunderstanding between the two of them and ml's difficulty in showing emotions ended with her disappearing to who knows where. it would have been better to see the two of them getting closer little by little. cliché plot but i think it's better than the plot so far. it frustrates me that he really cared about her and the baby and she'll never know that (used Translator sorry for mistakes)

AGREED.
I always hate the fact authors ignore, erase or simply don't talk about the other person. Which is why I honestly think a reverse isekai would be nice for once, in which we see the troubled medieval lady get send to another place/world/switch with the MC from our world and she gets a happy ending as well. Sure, it might not be as interesting to some (I personally would find it MUCH more interesting tho tbh) but it's definitely a nice idea and could even work as a seperate story, kinda like a prequel-sequel or alternate timeline thing the author could publish.
And I don't even think it can be called a cliche plot in a bad way if we see them fix their issues. I prefer that kinda plot over isekai stories at this point, I have read more isekai that ignore a troubled person instead of historical themed stories that actually bother adressing the issues.
(Your translation was very accurate I believe, no worries.)
