[ hinata's a little stunned that tsukishima is showing that he has Actual Real Feelings more than anything else--it's the first time he's ever even heard the guy say something nice, let alone have feelings about it, and he stares at him with his mouth open, though it's not meant to be rude.

eventually, he shuts it, though, bristling. ] What--I'm not gonna do that! [ because the idea feels ridiculous, even if he's not able to disseminate why out of his head besides a giant red exclamation point that says no. ] It's not like I'm dating you--euuuugh--and, anyway, who cares about that kinda stuff!!

[ hinata inhales a big breath and promptly jabs tsukishima in the chest with his finger. ] Besides, as long as you're nice to him, it's okay!! Cause he's the best, and you better make sure that he feels like the best all the time, or else!
