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.
It all started with that chord I played.
.بدأ كلّ شيء بذلك الكورد الذي عزفته
Es war ein Fehler, diesen Akkord zu spielen.
Todo comenzó con ese acorde.
Todo comenzó con ese acorde.
Je suis tombé
sur le mauvais accord.
Quella volta, il suono prodotto
 dalle corde era stato orrendo.
Tudo começou quando toquei aquele acorde.
Всё началось с сыгранного
мной аккорда.
