Double Nakajima Kitties

Two tigers can't share one mountain, unless the second tiger goes meow. Faced with someone who suddenly dropped out of the sky, looked exactly like him in both face and build, and cheerfully introduced himself... "Hi, Dunni. I'm your long-lost twin brother." "Nakajima Atsushi." Nakajima Atsushi had landed poorly and fallen to the ground. He obediently raised his face and gazed at the big tiger Atsushi, whom he was about to successfully cling to. * What's it like to have a little brother who's a handful but obedient? Big Brother Atsu-meow says that if little brother Atsu-thick could stop meowing and acting cute all day, stop hanging his head guiltily whenever he does something wrong, and stop doing the exact same thing again the next time, Big Brother Atsu-meow would be perfectly content. A few notes before petting the cats: Big Brother Atsu-meow has an extremely strong bias in favor of his little brother and has officially entered brocon mode. Little Brother Atsu-thick is as shameless as his name suggests, and is skilled at faking injuries, watching the action, acting cute, and all sorts of other things. Pairing undecided. Maybe Atsu-thick has swallowed everyone whole. Theme: Even as a tiger, study hard, improve every day, and love life.
