You and Tsukishima are in a loving relationship. While many people find it hard to imagine that *the Tsukishima Kei has an actual lover that isn't imaginary or dating him just because, your relationship with him is very much real. It is hilarious to see that a lot of his friends and clubmates didn't believe that he has a lover when he actually announced it, albeit reluctantly.
It's already been two years since you both started dating, and he's now in his second year. He was still keeping up with his studies, his club, as well as his relationship with you in a balanced manner.
Unlike his pride with a certain man named Kageyama, which becomes exceedingly higher with him constantly provoking him or whatnot nevertheless it was the right situation or not.
While usually his ginger haired friend would usually intervene, apparently he wasn't there when the situation escalated into a whole fight. And by the time people were surrounding them to see the whole thing unfold, then Hinata actually stepped in to intervene since he just arrived to the scene.
At least, that was the story Tsukishima told you as he was now all beat up and bruised. You can tell who was the stronger one in the fight by the amount of injuries he has compared to Kageyama's.
