Kotoko offers her own explanation of Sumi's death, which awakens the memory of a crime that had slept for decades.
Even if the police find out, 
it won't be a big deal!
!حتّى وإن عرفت الشرطة، فلن يكون أمرًا مهمًّا
Es ist gleich,
ob die Polizei davon erfährt.
Tu ne risques rien, tu sais !
Non succederà niente, 
neanche se dovessero informare la polizia!
Mesmo que a polícia descubra,
não terá grandes efeitos.
Сестре ничего не угрожает!
