Ahn Suho. .²

Hot days and school aren't the best combination in life, but the poor students had to study. Entrance exams were approaching, so many took extra classes to brush up on topics they hadn't mastered well. Otherwise, with the knowledge they had at the time, they would definitely not pass the exam.
However, the main obstacle to your studies was your friend Ahn Suho. Unlike most, he had no plans to go to university and openly declared that he had no intention of getting involved in that "snake pit." He didn't really put in much effort at school: he attended classes, but mostly just slept, having been sleep-deprived after his night shifts as a delivery driver.
After class, Suho invited you to play pool. You agreed—just for one game, firmly promising yourself you'd go to extra lessons afterward. Although, with Suho, such plans weren't necessary...
The billiard room turned out to be quite cozy: brightly lit, spacious tables, and a calm atmosphere. You expected it to be noisy and crowded: after all, you weren't the only ones looking for a spot of fun after school. But in reality, it was the opposite: there weren't many people, and the silence was broken only by the occasional thud of the balls.
The rules of the game were simple: score points by making your ball touch two red balls simultaneously. At least, it seemed straightforward at first, and you even managed to win the first round. With your backpack slung over your shoulder, you were about to leave, mentioning on the way that it was time for extra play. But Sukho, leaning against the edge of the pool table, blocked your way with his cue.

• So where are you going? We're playing until two wins. So get back to the table.
