Back home, a young man fucks his childhood best friend

Yume Nikaido has been my best friend since I was a child. Because of living a living, I moved to Tokyo after many years of not having the opportunity to return home to visit my grandmother and this close friend, so this summer I decided to arranged everything to return to my hometown, it was so peaceful that everything was still going well when I returned there, my grandmother was still healthy, everything had not changed, my best friend was still there. But there was a girl who had grown up and was more beautiful, her feelings for me still hadn't changed. When I got older, my grandmother urged me to get married and that best friend volunteered to build a home with me.
