Saying goodbye to Teacher He, I passed by the former music classroom.

　　I inexplicably stopped in my tracks.

　　My 18th birthday was spent at school.

　　Zhou Yun secretly brought me to the music classroom to celebrate my birthday.

　　He played a guitar and sang a song for me.

　　[Someone has settled in my heart.

　　Our appearance was so small back then.

　　We were like people learning to say love lines.

　　Even with missing teeth, your pronunciation is precise.

　　I'm looking for the person in that story.

　　You are an indispensable part of it.

　　Small hands holding a little person.

　　Guarding a small eternity.] After the song ended, he raised his eyebrows and proudly asked for praise, "How was it? Didn't your brother sing well?" "I sang ‘Xiaoxiao’ for Xiaoxiao." After saying that, he laughed foolishly for a while.

　　"I don't believe that you can listen to me sing and still be able to listen to others." Zhou Yun whispered and threatened me softly, "From now on, you are not allowed to listen to others sing." I naturally knew what he meant.

　　My face immediately turned red.

　　It all started during a chat with my classmates.

　　I unintentionally mentioned that in the future, the person who confesses to me must sing "Xiao Xiao" and then I would agree.

　　Zhou Yun found out about this.

　　He took it seriously in secret.

　　I don't know how many times he practiced before he sang it in front of me.

　　The two of us exchanged a knowing look.

　　Our ears turned red.

　　Now everything has changed.

　　The promises of our youth were too light.

　　I took out my phone and deleted the chat records from the three years of high school one by one.

　　After leaving school, I almost collapsed on the ground.

　　Luckily, someone kind helped me.

　　My body's reaction reminded me that I didn't have much time left.

　　I calculated and realized there were three days remaining.

　　Fortunately, I had already done most of the things I wanted to do.

　　In the end, I returned to the old neighborhood.

　　That was where I first met Zhou Yun.
