Mizuhara has lost the key to her apartment and comes to Kazuya for some reason... and she's not the only unexpected visitor!
There's no point in thinking about it.
لا جدوى من التفكير بالأمر
No tiene caso darle vueltas.
Darle vueltas es inútil.
Peu importe, dans le fond.
È inutile chiederselo, no?
Não vale a pena ficar
pensando sobre isso.
Что толку об этом думать?
