Luka's storyline headcannon

Ok, so I've been thinking, what is Luka's role in the Love Square?

Sure, Marinette will be attracted to him and that'll probably cause her to doubt her feelings for Adrien 'cuz, he's apparently into Kagami, she's aware that he sees her as a friend (that hurts, man), she's too shy to confess her feelings, etc, and so, Luka appears.

Now, the real question would be how would she take those doubts seriously since Adrien wouldn't technically care if Marinette dates Juleka's brother or not. But here is my theory: in Luka's debut-in which I guess he'll be akumatized-, Adrien will probably notice Marinette's attraction to him, and since he "knows" she has a crush, he will probably assume it's him. So he'll be trying to get them together. But, because Ladybug will probably talk to him after they have save the day from his akumatized form, she will probably show interest in him as well, worrying Chat, like, "Wait, so this is the guy she's in love with?! But Mari loves him too!! Hold on, that's it. That's the solution, I just have to try even harder to help Marinette end up with him!"

And don't tell me he isn't capable of doing such things because of jealousy because... Ehem... Copycat.

So yeah, Marinette will struggle with her feelings because, not only Adrien feels differently, but he's trying to set her up with another! And, meanwhile, the little dude is practically giving the love of his life to someone else...
