That's totally extremely stupid and such a mono way to think. The semes poly considering that he's dating those girls means he loves them too. Loving the uke doesn't erase the fact that he loves them too. And dropping all of them for just one person?????!!!!???! Then he's no poly he's just a complete douchebag and asshole.
So he's definitely fucking all those girls
I mean, they surely didn't show that Luca was cheating or gave definite hints that he would in the near future. The problem lies in how normalized cheating is for Luca. He is not a bad person, it's just that the culture is different. If it comes that Luca falls in love again (and notice that he fell in love with Makoto at first sight) then the possibility of cheating is very high.
But whatever, it is still fiction, in my head, they will live happily ever after.
but why is everyone ignoring that Luca is polyamorous? I mean, I don't want my baby Makoto suffering bc of that (they don't show that so I think it's okay, but for a monogamous person it would be a real sock)
Also, he said it is illegal for gay couples to date there, so I am a little worried about that as well.
Anyway, don't mind me, I'm probably over analyzing
