Sentaro and Ritsuko attend Christmas mass together while Kaoru decides to attend a Christmas party at Seiji's house, hoping to distance himself from them. Finally aware of her feelings for him, Sentaro apologizes to Ritsuko for not knowing how she felt, but the two end up renewing their conviction that they are just like family to each other. Junichi visits Yurika to tell her that he has accepted an offer to work for Arita's publishing company in Tokyo. Ritsuko talks to Yurika and decides to let Kaoru know how she feels. Kaoru insists that Sentaro should talk Junichi before he departs, but Sentaro displays an indifferent attitude. Sentaro sends Junichi a letter of challenge to one last session with the band. The two duke it out to "Four" by Miles Davis. At the subway station at night, Junichi is approached by Yurika, who begs him to take her with him, but he insists that they should part ways. Just before the train starts moving, Junichi hears Yurika's parents at the station, angry at her for leaving in the middle of a matchmaking meeting they arranged for her. Junichi pulls her into the train at the last moment, and the two embrace as the train leaves the city. Back at the record stop, Kaoru opens the piano fallboard and finds a pair of blue gloves Ritsuko knitted for him.
