It starts the moment he sees you struggling with your bag — or even just holding it. Baji: "Give." He was already slinging it over his shoulder like a warrior preparing for battle He doesn’t care if it’s light. He doesn’t care if it looks ridiculous. Carrying your things is not optional.

Once, Mitsuya tries to tease him: "Since when are you a pack mule?" Baji just shrugs. "…I wanna help her. Problem?" No one says anything again. And when he thinks you’re not looking, he adjusts the strap so it doesn’t hurt your shoulder the next time you wear it.
