Fushimi Roku borrowed the file, read it carefully, and realized his colleagues had it wrong; it wasn't solely Yakai Mutsumi who stabbed her husband to death, but rather both sides stabbed each other.
Only Yakai Mutsumi had thicker fat, so Kuroda Kotaro's stabs didn't injure her internal organs, allowing her to survive and successfully retaliate against her husband.
This shows that ancient generals having a big belly is reasonable.
Minamoto Tamako blamed herself terribly, believing that her failure to mediate properly inadvertently led to the outbreak of the couple's conflict, indirectly resulting in the murder... If she had gone to the Kuroda Family last night to dissuade them, perhaps she could have saved a life!
The other colleagues were long used to such matters and didn't take this incident to heart. The police had mediated several times, yet the couple wouldn't listen, who can be blamed for that? Should the police install cameras in the couple's home?
