My son's friend, Hayato-kun, confessed his feelings to me again. ...The thing is, this isn't the first time Hayato-kun has confessed to me. Back then, he was still a high school student, but now he's a working adult. He looked like a proper grown man. I thought maybe I could date him for a little while now. For the first time, I decided to respond to Hayato-kun's feelings. I intended to teach him what an adult woman is like, with something called a one-day date.
