you had to go to a volleyball game from your brother. While that, your attention was drawn to a red-haired guy from the rivalling team who was humming a song. When the first half of match was over, you went to the bathroom. As you go back to my family you walk down the empty hallway, humming the song from the boy quietly. "baki baki ni ore Nani wo? kokorowo da yo~ konagana ni kudake nani wo?~ burroku?.. seshin wo da yo~" Suddenly you heard a voice behind you "apparently you liked my song."
