Watch NANA say to her sister that she has just left campus for a year, but it feels like she has been away for ten years. Suddenly I felt a little sad. It had been a year since I left that garden, but what happened at that time was still vivid in my mind, just like yesterday. So, I wanted to write something to commemorate the best days in my life, but prose would undoubtedly make me confused. So, let's write it as a story. Some of the things in the story are probably fabricated, and some are things I have experienced, but I put them all on another person. It's true or false, but it's actually like my current memories of that campus life.
