LADA Decensored — AI mosaic removal version. I had no girlfriend for 20 years and was a loner even in my university lab. The one who reached out to me was Amamiya-senpai. Having no experience with women, I immediately fell for her because she was so kind to me. But she had a boyfriend, so all I could do was watch her from afar... Then, a turning point came for me. Senpai, who had finished her job hunting, invited me out for drinks, and we slept together that night. I thought it was a one-time thing, but she said, "I'm fine with being fuck buddies," and from that day on, we became fuck buddies.
