thinking of suna being so proud of the scratches osamu leaves on his back. instead of hiding them, he will nonchalantly change his shirt with his teammates and if anyone asks, he will answer with a smirk, "aren't they pretty? they're my lovely boyfriend's work of art."

one time it's komori who can't help but to stare at the red marks on suna's shoulders and upper back. suna only spares him a short glance, eyes glinting in mischief. "take your time staring, osamu's pretty proud of 'em." komori becomes a blushing mess while suna only snickers.

this headcanon has been living in my head rent free and i don't care what everybody else says i will die on this hill believing this.
