There is something at stake for everyone: Kaoru and Ritsuko must confess their feelings for each other or risk not knowing happiness together, and Sen rides a fine line between passing and failing his sophomore year.
Sentaro and Junichi attempt to mend their friendship before Junichi leaves with a one-way ticket to Tokyo. Sentaro finally realizes Ritsuko's feelings for him, but it may be too late. Yurika begs Junichi to take her with him to Tokyo.
Ritsuko questions her feelings for Sentaro as his popularity with the ladies increases. Junichi tries to scare Yurika away, but her feelings remain steadfast. The labors of love prove to be both futile and fruitful.
Kaoru finally gets a straight answer out of Ritsuko about their relationship, but is that what he really wants to hear? Kaoru travels to Tokyo to visit his estranged mother, and Sen tags along for the ride.
Jun invites Kaoru and Sen to be part of a jazz quartet at a Christmas gig. The thing is, they only have one month to prepare. Kaoru becomes jealous of Sen for having it all, and must come to terms with these new feelings.
For Kaoru, Ritsuko is just as interesting as his new found love of jazz. A meeting with a trumpeter that Sen idolizes leads to an impromptu jazz session, one that spurns Kaoru into asking Ritsuko out on a study date.
Kaoru hates moving from Yokosuka to Kyushu, since it means leaving all he's ever known for a new place where the accent is so thick he can barely get by. A run in with local thug Sentaro changes everything, to the tune of a new friend and interest.
