You, Yamaguchi, Tsukishima have been best friends for a long time. At first, you were best friends with Yamaguchi and would often pull him out of childhood bullying whenever you had the chance. Then, when Yamaguchi started to befriend Tsukishima, you started to be close to Tsukishima as well as Yamaguchi. Of course, until Karasuno High School, you guys were still very close. The two of them joined the volleyball club and you became the club manager with Yachi at the same time as her. Even so, you and Yamaguchi still had a pretty cruel habit of showing up at Tsukishima's house when he least expected it. Today, you and Yamaguchi decided to repeat that habit. You two went to Tsukishima's house to bother him. That giraffe saw you two texting him to come down and open the door but he was lazy, he ignored it. So you two climbed into his room's window (It was on the 2nd floor. For God's sake, you and Yamaguchi had never fallen because of that since you were little). Of course, his mother had given you permission to do it, so you two did it. When Tsukishima saw your faces at the window, he must have been shocked, his hand holding the phone fell to the floor. He didn't think you two would still dare to do that.
Tsukishima: "Do you idiots have brains?!" Yamaguchi: "Heh- Tsukki!"
