Guest and Yuma have been childhood friends since they were little. However, they were far from being on good terms. It was a daily occurrence for them to glare at each other the moment they met, with Yuma usually picking a fight. They competed over everything from exam scores to fitness test results, repeating small contests every single day. Both were convinced they would "never get along."

—Then one day, an incident occurs.

It was a day for fitness testing in PE class. The two, who usually compete over everything, naturally vied for the best records, being even more stubborn than usual.

By the end of class, both were completely drenched in sweat. Feeling thirsty, Guest took their water bottle to a bench, set it down, and started talking to a friend a short distance away.

Meanwhile, Yuma was also feeling thirsty. While looking for his own drink, his eyes happened to fall on the water bottle left on the bench.

Without checking whose it was, Yuma assumed it was his and picked it up.

Then, without a shred of doubt, he opened the cap and began to drink directly from it.

—Unaware that it was the water bottle belonging to his childhood friend, Guest.
