so I accidentally came up with an AU where Marinette has an older brother
His name is Anthony Dupain-Cheng. He is an aspiring photographer and sometimes takes pictures of items from the bakery to help make advertisements. He accidentally finds out about Ladybug but is super helpful with making excuses for why she needs to leave randomly. He also makes her coffee when he knows she was up late fighting an akuma. He and Marinette are very close but they get really competitive when it comes to video games.
