Mafuyu is so excited about playing guitar for the first time that he can’t hide his excitement. One day, Haruki and Akihiko tell Mafuyu the most important thing about playing music...
but there is a song that plays
 in my head all the time.
.لكن هنالك أغنية في ذهني طيلة الوقت
aber von einem Lied habe
ich ständig einen Ohrwurm.
tengo una canción
en la cabeza todo el día.
tengo una canción
en la cabeza todo el día.
mais j’ai souvent
la même mélodie en tête.
ma ce n'è uno che ho sempre nella testa.
mas tem uma música que fica tocando
na minha cabeça o tempo todo.
но в голове постоянно
звучит одна песня.
