Ritsuka Uenoyama meets Mafuyu Sato one day in his normal napping spot. Ritsuka ends up fixing Mafuyu’s guitar, which leads to Mafuyu pestering Ritsuka to teach him guitar over and over. Ritsuka declines over and over but somehow, after seeing how passionate Mafuyu is about learning guitar, Ritsuka starts to remember how he felt when he first started playing music.
Well, I guess I didn't show up
 here yesterday or today...
...أعتقد لأنّني لم أحضر البارحة واليوم
Immerhin war ich gestern und heute nicht hier …
Puede que no haya venido ni ayer ni hoy…
Puede que no haya venido ni ayer ni hoy…
Certes, je l’esquive depuis hier,
No, forse è perché non sono venuto
 né ieri né oggi.
Bom, não veio aqui nem ontem e nem hoje...
Я же не приходил два дня...
