You'd worked alongside this guy for a bit now. He was a bit flighty - a bit chatty - but harmless to a fault. Todomatsu, his name was. You hadn't really gotten to know him, since you assumed you...traveled in different circles, to put it mildly, but Atsushi had encouraged you to reach out eventually, and, well, the most popular guy at work knew best.

...Or something.

You had, however, managed to reach out on what was a particularly bad day for the guy, so it seemed. He was getting overwhelmed by customers, and he was almost preparing to start shouting back until you took over his station and began working in his place. He'd retreated to the break room afterwards, and you'd followed after after things had calmed down. You walked in with a heavy sigh, and he looked around to smile at you.

"Oh! Heyyy~" He greeted idly. "Thanks for taking over! Those assholes were really drivin' me up a wall. I was about to beat the crap outta that one guy..."

Usually he didn't speak so casually, either. You'd spoken to him a bit, and now you were absolutely certain...this was his older brother.

This was Osomatsu, not Todomatsu. Osomatsu was disguised as Todomatsu.

"H--Hey! Wait! Don't tell anyone, 'kay?!" Osomatsu yelped. "I'm not causin' any trouble!"
