who cooks normally? Both of them would cook. They’re both good cooks and would take turns cooking or just have the one who’s less tired and more willing to cook do it. Taiga might end up cooking more often than Tatsuya because he’s more likely to go to the kitchen and start preparing a meal though.
how often do they fight? They fight sometimes. Taiga is the type to annoy Tatsuya even involuntarily while Tatsuya tends to keep his emotion bottled up and not voice them. Taiga would be ok with only Tatsuya by his side which is not Tatsuya’s case. But Tatsuya also learned his lesson after Yosen’s defeat against Seirin and is trying to open up a bit more to Taiga… which wouldn’t prevent fights, just make them less frequent.
what do they do when they’re away from each other? They text each other while doing their regular activities, both attending their classes, hanging out with their friends and practising basketball by themselves to improve their skills and compare their respective improvements on one-on-ones later on.
nicknames for each other? Tatsuya and Taiga. That’s how they always called themselves and they wouldn’t change it.
who is more likely to pay for dinner? Both are as likely to pay for dinner as the other. One would pay once while the other would pay the time after.
who steals the covers at night? Tatsuya isn’t one to move at night so Taiga would steal the covers. Tatsuya will wake up from the sudden cold and will switch position as for his chest to get heat from Taiga’s back, wrapping his arm around his torso to spoon him while putting back the cover over both of them.
what would they get each other for gifts? Tatsuya would get Taiga basketball equipment, shoes and outfits to practice since he knows he has problems finding the former in particular in Japan due to his size. Taiga may ask Tatsuya what he wants since he wants to make Tatsuya happy but wouldn’t know what to offer him.
who kissed who first? Taiga kissed Tatsuya. I like to imagine it in an attempt to have Tatsuya shut up or stop whatever bullshit he may have given Taiga which indeed was an effective way of dealing with him.
who made the first move? Taiga since he wanted Tatsuya to acknowledge him as more than a brother.
who remembers things? Tatsuya remembers more things than Taiga in general even if Taiga can surprise him sometimes with little bits he recalls that Tatsuya might have thought irrelevant and had forgotten about.
who started the relationship? Tatsuya took the initiative to start the relationship seeing that Taiga seemed interested enough and wanted their relationship to evolve despite their recent issues.
who cusses more? Taiga cusses a lot more than Tatsuya does.
what would they do if the other one was hurt? Taiga would be extremely worried and angry at whoever did this to Tatsuya. It’s not unlikely that he would get to fists to show the person that you shouldn’t mess with him. As for Tatsuya, he’d show less concern even if he’d make certain Taiga is fine before beating up the one who hurt him or at least making sure they’d regret their decision of hurting Taiga.
