My name is Souta Tanihara. I'm sorry to suddenly show you this kind of'slut'. It's been eight years since I got married to my wife, Nozomi, and we've been busy with each other, so we don't have any children yet. However, we have helped each other with Nozomi and have lived a happy married life so far. But ... I wonder if something like that happened between my neighbor's husband, Sato, and Nozomi. I didn't expect it until that day when I went up the elevator to pick up my forgotten items ...
