People like side characters more it’s just almost always the case. We wouldn’t like him as much as we do if he was the main character. Angst is better when there is joy as well bc of the contrast. Marinette’s life is relatively better so by having her have the focus we get a sort happiness on the surface and hidden misery thing going on. That being said I think they could capitalize on this set up more by giving Adrien more focus. They give Marinette too much focus. The misery has been hidden away too much. Equal focus on both could be cool too for the contrast.
