ABP-026 Stepmother and teenage son

When I was young, my mother ran away from home with another man. My dad cried every night, which made me very sad. However, I still behaved at school as usual so that people wouldn't find out about my family's affairs. A few years later, my father remarried, and I had a new family, a kind and gentle mother, and an older sister who was a bit of a gamer. I really feel extremely happy. A few years later, I left my hometown and went to study at a university in Tokyo. Because it was the first time I had to live alone, my father was very worried, but he was also very proud of me....
