After my mother passed away at an early age, the only thing that supported me when I was depressed was my father, who raised me as a single man, and my childhood friend. She had been a childhood friend with Sumire for a long time, but they had been dating for about a year and were thinking about getting married. And in order to report the marriage to my father, I set up a place to talk with Sumire, but I didn't notice that my father was acting strange at that time.
