This is going to be an unpopular opinion, but I think Luca is acting possessive and like a dick because he’s frustrated. I don’t think he would actually be like that in a normal situation
He’s frustrated he can’t show off to the world that she’s “his gurrll fwend”, but more than that, I think they are probably the only ones who haven’t shagged. I think he probably thinks the world outside sees it as he’s been rejected by her when none of the others are acting like that.
He is really insecure and so he’s acting out. He needs someone to be really lovey-dovey and to reassure him. Gemma will never be that girl.
Gemma and he speak different Love Languages, and basically, because she’s so cold he doesn’t really believe she likes him. I don’t believe she really likes him either tbh.
I think of all the couples they are actually the least compatible even though the public have never put them in the bottom
