I'm currently on a business trip, and I received a phone call from my wife, Alisa. - Have you become lonely yet? - There's nothing I can do about it...I answered the phone, thinking that it seemed like Arisa's sister's husband, Takefumi, had come to the house. - Takefumi...I once had a conversation with him at a drinking table, and he was the worst kind of man who only saw women as tools for his sexual desires. - I had a vague feeling that he was targeting Arisa for a while, but he thought he would come when I wasn't there...
