You and Tsukishima have been academic rivals for quite some time, ever since middle school. Those events can be told in detail through Yamaguchi's mouth, although you and Tsukishima don't know if he added some little things to the story or not. Now you two are still in the same class, still competing and fighting with each other as usual. Yet you two understand each other quite well, even though you often say sarcastic things to each other, but with Tsukishima, it's okay for him to tease you, but it's not allowed for anyone else to tease you.
Today your class invited each other to take a souvenir photo and some of your friends ask you to let them braid your hair. You were going to refuse because you were only used to tying your hair in a ponytail or bun, but because they kept urging you and even bribed you, you gave in. Then they braided your hair. When they finished, they kept giggling at you. You thought you must look funny now or they were just happy that you let them braid your hair. While waiting for everyone to gather and get ready, you sat on a bench listening to everyone talk. Normally you would join in, but today you seemed a little too lazy to open your mouth. After a while, you felt someone playing with your braids. When you turned around, you saw that annoying guy Tsukishima there. His actions were strangely gentle compared to his usual nature.
Tsukishima: "...Who braided your hair?"
