First, Happy Birthday, anon! I hope your day has been full of delicious cake, good friends, and birthday wishes ❤
Good question! I’m not sure Satya or Hanzo are the type to celebrate birthdays. I think they’re too busy with their own concerns to devote time to celebrating them getting a year older. They might be aware of it but I doubt they do anything for themselves.
I think I could see Hanzo celebrating her birthday though, if he ever found out what it was (since he would never ask and she would never tell). He might surprise her in this fashion but he’d stick to something simple and ensure it’s something Satya actually enjoys. He might bring her a book she’s been talking about, some new teas, or even a very carefully arranged bouquet of blue chrysanthemum.
Once Hanzo makes the move to give her something, Satya will always make sure she gives something back, even if it’s not her birthday, because she feels it’s good to repay a kindness. She’ll get him things that he’s talked about in the past, even if he hasn’t said he’d particularly want it. He once mentioned that he did calligraphy as a teen and she ended up giving him some new brushes.
Birthday gifts when they’re romantically involved would always follow with a chaste kiss to the cheek. Nothing fancy between these two but they’re quite happy. ^//^
