While cleaning my room, I found a nostalgic photo from a gap in the cardboard box. It was a two-shot photo with my first girlfriend. As I looked at the photo, I remembered the past. The first time I met her was at my best friend's house. Yes, she was my best friend's mother. I went to my best friend's house for some reason. Of course, because I wanted to see her. I was still a child and didn't know what to do with this feeling. One day I went to my best friend's house. That day, she was the only one there, and I was more nervous than usual. She asked me if I had a crush on someone. My heart was beating so fast that I thought it might break. She said that if I regretted it, I should confess. I boldly confessed to her. She laughed, saying, 'Even though I'm such an old lady?' To me, who couldn't say anything clever, she gave me a kiss and said thank you...
