Continued: A record of her having sex with her friend for three days (tentative) as she said she would be leaving her house on a family trip for three days.

I received a call from Nanami, who I hadn't seen in eight years since graduating from university. They all get together on the eve of their classmate's wedding, so they're going together. Since she used to be a sex friend with Nanami, she left the house secretly without telling her now. Just eight years ago, we had sex over and over again, without telling her at the time. What was Nanami trying to contact her? Do you remember back then? Maybe I'd contact you because I wanted to get back together with me? No, I can't believe it...and as I was thinking about it, the meeting time with Nanami was approaching.
