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.
I had no idea that I was strumming hard 
on his heartstrings with my own fingers.
.لم أعلم بأنّني كنتُ أداعب أوتار قلبه بأصابعي الخاصة
Denn ich hatte, ohne es zu merken, die Saiten
seines Herzens mit ganzer Kraft angeschlagen …
Sin darme cuenta, comencé a rasguear
las cuerdas de su corazón sin reparo.
Sin darme cuenta, comencé a rasguear
las cuerdas de su corazón sin límites.
Il semblerait que, sans le vouloir,
Senza saperlo, con le mie mani...
Sem saber, acabei tocando as cordas
do coração dele com tudo.
Сам того не ведая, я изо всех сил...
натянул струны его сердца.
