Your parents are divorced. Your dad still lives in America, while you moved to Japan with your mom where she met someone new. They eventually got married and had a child, your half brother Taki who is now 7 years old, making him 13 years younger than you (you being 20 and all). Your stepfather teaches volleyball, which means that Taki obviously had to become a huge fan of the sport too. And that leads you here: attending a volleyball match between the Schweiden Adler's and MSBY with Taki, since your mom and stepfather are out of town for the weekend. Taki chose to wear his favorite jersey, that of the Adlers' star player Ushijima Wakatoshi, the name Ushijima plastered on the back of it with the number 11 underneath. Your family isn't that well off, so your seats don't have a good view on the court, but Taki doesn't mind. He's completely over the moon, talking your ear off the entire time with volleyball facts and knowledge about the players that you don't know where he got it from... well probably from your stepfather if we're being honest. The game is intense, leaving Taki on the edge of his seat, but you don't particularly care about the sport, never have, and most likely never will. Nonetheless, you like seeing Taki so happy and excited. The game ends two and a half hours later, the Adlers winning 3 sets to 2. You're about to leave, like the rest of the crowd, but Taki insists on staying behind so he can get a proper look at the court, so you wait. Once Taki is satisfied, you take his hand and lead him towards the exit. He insists on having to go to the bathroom before you leave, so you let him, and wait next to the stairs. After a while, when he's still not returned, you start to get restless, blaming yourself for being so stupid as to let him go alone. Countless horror scenarios run through your head, each one worse than the last. You weave through the crowd, looking for him, asking people if they've seen him and calling his name. After another excruciating ten minutes, you get to the section where the players sometimes give autographs and selfies to fans after matches. This time, there's only two lines, so most likely only two athletes doing fan service. The shorter line is quickly gone through, and then you turn to the other line, pushing through the people, apologizing the entire time until you get to the front only to see... Ushijima Wakatoshi, kneeling in front of Taki, patiently signing his jersey while looking around searchingly, most likely keeping an eye out for his parents.
