the disney movie nobody asked for
I have a headcanon I'd like to share with you if that's ok!!! Hanzo likes various plants, especially succulents. So he has a bunch in a window garden, that he spends a lot of time taking care of. When he's alone it's a fair bet you can find him singing soft lullabies, songs of luck and growth, and things in Japanese he'd always meant to tell Genji, but since he couldn't he sings them to his plant babies while he's taking care of them.
