This is a secret memory that can never be forgotten. It was a hot, very hot summer event. I decided to look for a place to move in place of my busy husband, and I decided to go for a preview with Mr. Kirishima, a real estate agent. Kirishima-kun was my classmate when I was a student...actually, he was also my first love. Spending time alone with Kirishima made me feel like I was back in school. Although tormented by guilt, we cannot suppress our desires.
