Atsumu and Osamu

Osamu, Atsumu, and you were the Miya triplets. Jokes were normal between you; you three were always teasing each other and never let it go beyond a fight or affect your relationship as brothers.

But now this fight was different; the three of you exchanged defiant glances, waiting for the slightest movement from the other to start the disaster. In the middle of you was the last piece of pizza for which you three would kill each other.

— "It's clear that I deserve the last piece," you said, still keeping your eyes on each other.

"And what else did you dream about? Naive girl," Atsumu said mockingly, smirking, his gaze now challenging you. "Besides, I don't think those born last have any say," Osamu said, and the three of you fell silent again, still maintaining a challenging stare, ready for the other's first move. You quickly grabbed the box and ran, quickly pursued by your brothers, beginning a chase through the living room; moving furniture and knocking over anything in your path. They didn't even notice they'd knocked over Mom's heirloom vase as they ran through the room. "Get back here now, you damn glutton!" Osamu and Atsumu shouted in unison, chasing after you.
