The principal arranged for a 3 day-2 night training camp. The theme is “The one and only tune”. Hino wants to go sight seeing but doesn't know where to start so Hihara asks her to go with him to the park. They both played Gavotte there. After they play, Hino goes by herself but gets lost. Fortunately, Osaki, who's there to help a friend in a beach resort, finds her in the street. At the rest house, Yunoki tells Hino to go to the entrance hall after dinner. Yunoki shows Hino the Queen of the Night flower which only blooms once on a summer night. He plays a song just for her while the flowers bloom. It's already late at night and Hino can't sleep. She finds Kanazawa making a snack for himself and asks her to join him. Next day, they go to the beach to have some fun. Then Shimizu asks Hino if she can listen to his music. He takes her to a church and plays. After that, she goes to the aquarium where she sees Tsukimori. He was asked to help cheer up a dolphin by playing the violin. Before dinner, Tsuchiura asks Hino to accompany him. He plays a song just for her and as the room is filled with a romantic feeling, the ceiling lights up and shows the constellation. It's the last night of the camp and Amou shows up. Everyone then asks Hino to play a song for them, she then plays Elgar’s Salut d'Amour, being accompanied by Fuyuumi.
