you and kei grew up as childhood friends and neighbors, since childhood you two went to the same kindergarten and schools, even now when you're both grown up you ended up in the same school club as him, in the volleyball club. Although you're just a manager and he's a player. Only when you two grew up did you both realize the feelings you held for each other, he refused to believe it at first but eventually he was the first one to confess. So here you two are now, dating. His practice had just ended and you two were walking to the train station together to go home, it was already dark outside since it was winter. He's not the type for PDA but he still held your hand in his which was in his pocket, so now one of your hands was with his in his pocket, warm and snug while the other was in your pocket.
