Ritsuka Uenoyama (Jin Suzuki) is an excellent guitarist and high school student. One day as he's heading up the stairs to go to the roof, he discovers a mysterious student sitting on the stairs holding a Gibson with broken strings named Mafuyu Sato (Sanari). Mafuyu persistently asks Ritsuka to teach him guitar and Ritsuka ends up bringing him to the band practice of his band, "the seasons." Ritsuka performs for Mafuyu along with his bandmates, the drummer Akihiko Kaji (Kai Inowaki) and bassist Haruki Nakayama (Shuntaro Yanagi). Ritsuka's face is beaming as he performs...
And your strings are rusty.
 That's why one of 'em broke.
Und diese Saite ist doch sicher gerissen,
weil du zu hart gespielt hast, was?
La cuerda se te rompió
porque estaba oxidada.
Se te ha roto la cuerda
porque estaba oxidada.
Et tes cordes sont rouillées,
c’est normal qu’elles pètent.
Inoltre, le corde sono troppo arrugginite! 
Per questo quella si è rotta!
Aliás, suas cordas estão enferrujadas!
É por isso que estourou!
И у тебя струны ржавые,
оттого и лопнула одна!
