Then suddenly, a man named Tamami Kobayashi appears. Despite it being an accident, he demands money from Koichi, saying that he'll use it to bury the cat. Koichi can't process what's going on, but Tamami keeps pushing that he can't just leave after what happened. Koichi is filled with guilt, and then suddenly, a giant lock pops out of his chest...
My day started off with something 
terrible, so I was down the whole day.
بدأ يومي بداية فظيعة، لهذا كنتُ
مكتئباً طوال اليوم
Wenn der Tag schon so mies losgeht,
macht der Rest auch keinen Spaß.
Como tuve una mañana terrible,
estuve decaído todo el día.
Como tuve una mañana terrible,
he estado depre todo el día.
Après cette horrible matinée,
j’ai eu le cafard toute la journée…
Questa giornata è cominciata malissimo
e non ha fatto altro che peggiorare.
Comecei o dia com o pé esquerdo,
e fiquei arrasado o resto do dia.
