It was a long time later that I realized that that morning might be the happiest time of my life.
"An, An, why are you bleeding ?"
The sun was screaming again, and its hands were still groping my arms. I turned my head and saw that it might have scraped my elbow when I fell, and the blood had dried where the skin was scraped, so it was only now starting to burn.
"Yi Ping'an, wait for me here."
After a while, He Xubei came out of the community pharmacy carrying a plastic bag.
I was a little surprised. Was he concerned about me? "He Xubei, it's not that serious. It's not the first time we've fought. I'm used to it."
"Put your hands here and turn your elbows around."
I'm not sure if He Xubei heard me. He took out a small bottle of iodine, wiped the wound with cotton wool, and then took out a band-aid and gently put it on. He looked so serious. Was his frowning face worried about me? I was stunned and motionless.
"Alright, don't get your wound wet until it heals. Take the unused stuff back."
He Xubei stuffed the plastic bag into my hand, then he lifted up his bicycle with one hand and picked up the schoolbag on the ground with the other. I came to my senses and helped him pick it up with a servile expression: "He Xubei, thank you for today."
He took the bag and said expressionlessly, "No, I can't help much!"
"Ah?" I was a little uncomfortable with his change of attitude and looked at him blankly again.
"Yi Ping'an, you idiot! Has anyone ever told you that you are not suitable for being cute? As a girl, you should stop fighting in the future."
When He Xubei's back became a small black dot, I smiled. I held the still-smiling sunshine and trotted in the late spring wind.
"Sunshine, let's go back too."
When I lay in bed at night, He Xubei's image kept lingering in my mind. I couldn't fall asleep at all, so I just held my computer and wrote a Weibo post:

I met him today. He helped me when I was being bullied, and he even ran to buy me a band-aid when he saw me injured. The happiest thing was that I found out that he and I live in the same neighborhood!
