Tsubasa's classmates at karaoke are excited for Valentine's Day. Sayuri says she isn't interested but later bumps into Minami while gazing at the Valentine's display from afar. She then decides to ask Minami a question.
But hey, it's my fault for 
not cleaning up first.
لكنّها غلطتي لعدم تنظيفي أوّلاً
Es mi culpa por no ordenar antes.
Es mi culpa por no haber recogido antes.
Ma no! È solo colpa mia che ho lasciato
tutto in disordine.
Mas, ei, a culpa é minha
por não ter guardado tudo antes.
Ну ничего! Сама виновата!
Надо было сразу лишнее убрать.
