A quite familiar story in JAV movies, it is also a warning to young men who easily let their wives go to class reunions alone. Yua Mikami asked her husband to come to the class reunion party. There was Mikami's old lover there, so her husband was very worried, so he often made video calls to monitor. Who would have thought that the wife was so happy that she drank to the point of being so drunk that she didn't know anything. Her ex-lover took advantage of that opportunity to bring her in as a guest and force her to review the old story.
