if they all were in a relationship together tony and thor would make it their mission to loudly talk about how great bruce is and how much they love him just to fluster him. They brag about their great 7 phd owning boyfriend to anyone who listens
And they’re both super protective and Extra about showering Bruce with love, Thor always sneaks hugs and kisses and Tony always looking at Bruce with so much affection and softness. They never push Bruce to Hulk out if there’s a big fight, they just go in front of him shielding him like muscle memories, and sometimes the fight gets tough and both Bruce and Hulk can’t stand it anymore and Hulk would take control and be like, Hulk Here, Boyfriends safe. And tries his best to fight the villain with minimal damage, because Hulk doesn’t want Tin Man stress about collateral damage. Bruce would sometime ask Hulk to come out and spar with Thor because he knows how much Thor loves fighting with Hulk, and those days Tony would make them dinner (or he tries), whatever he ends up making Thor and a post-Hulk Bruce would happily eat them all, not necessarily because it’s delicious, but because 1) they are starving and exhausted and 2) they love Tony and who cares what the food taste like!
