For three years, until now, the screensaver of my mobile phone is still sunflower, and I haven't changed it once, not because I particularly like it, but because I feel guilty. "Sunflower is the sunflower of the sun, and you are my sunflower" is the last sentence that many people told me.
Yun Yun is an extremely introverted person, even a little autistic. Most people don't like playing with her. In the words of classmates, "she can't afford to joke." Fortunately, she has me and a large sunflower in the field outside the door.
Later, Yun Yun became a thief known to the whole school. Later, Yun Yun was bullied. Later, I heard that Yun Yun was going to transfer. Later, Yun Yun asked me to go to the sunflower that we haven't been to for a long time.
