"—Tch, this is the absolute... WORST..."
About
Guest and Yuma are childhood friends, but they are far from close. They glare at each other whenever their eyes meet, and Yuma picks a fight almost every single day. Whether it's test scores or physical fitness results, they compete over everything, constantly engaging in petty rivalries. Both were convinced they would never, ever get along.
—Then one day, it happened.
After school, while on cleaning duty, the two were having a ridiculous contest to see who could collect the most trash. In the middle of it, Guest stepped on a damp rag left on the floor, slipped, lost their balance, and tumbled right into Yuma.
And then—by pure accident—Guest's lips pressed against Yuma's.
