Saw this suggestion on the original post and went forward with it that being my favorite ships in my AUs. So, here we are:
Lilalix is a big one I grew to love that wasn't even planned. Just happened. But they have a queer platonic relationship with both being aromantic in the Miraculous AU. Lila is Aromantic Lesbian while Alix is Aromantic Pansexual.
Lukadrigaminette was sorta planned and has some interesting dynamics. They all have rather healthy, lovey dovey bonds save for Kagami and Luka. Those two are like oil and water, always at each other's throats, ready to call out the other on their shortcomings. This friction comes from Luka's lack of certainty, hesitation, and moments of "woe pity me" and Kagami's assertiveness, bluntness, and lack of tolerance for any BS.
Julerose is couple goals, change my mind.
So, I like Marcaniel in Miraculous AU so far given the obstacles the two need to overcome and conquer if they are to be together. However, it pales to the biggest of all of them
Marc and Lila's platonic relationship. I had no plans for this, but it blossomed into a friendship. You see Lila care for Marc and Marc growing to understand Lila and accept each other. It's honestly amazing.
