Invite the neighbor over for dinner and the outcome

Isn't it just a meal? I will cooperate with her as Hayato-san's fiancée. We are being advised by our close friend Hayato, who wants to dispel the lies he has told his mother. I am in trouble, and I have the enthusiastic wife pushing for cooperation with me as if it were a drama. And on the dinner day at the restaurant, I thought he would return after a few hours, but Hayato's mother had made a reservation to go to the hotel, so it seems difficult to return. After that, I did keep in touch with him many times, but by midnight, communication with my wife was cut off.
