It's just weird cus we had the whole thing of the MC dropping Rin's other personas and her trying to win him over, to sudden whiplash with some random plot about her becoming famous and if the two of them will stay together and ending in 10 chapters. Idk. I thought there was still plenty of story to tell with them being a couple and doing dates or whatever as an SoL. It's pretty clear that the mangaka got tired of it or didn't think it would remain interesting and tried to just wrap it up. I still think a MAJORITY of this series is really good, but man these last few chapters just leave a sour taste. To me it could've ended with a small timeskip of them just being married, having their kids ask about their 'harem' causing a lot of embarrassment from Rin. I mean the ending had NOTHING to do with what the series started out about and I think that's what made so many people upset with these final chapters. It's okay for series to start as one thing and slowly change, but again, this was over the last 10 chapters that we suddenly started to seriously focus on acting - which was always a background for the actual romance. But it ends practically conclusionless with everything.
