I don't know what I have in this short youth, and I don't know what I have lost. Perhaps it's like what Zhang Xuan sang in his song "About I Love You", "All I have is luck, all I've lost is life." In fact, it was already destined from the moment we met ~ me, you, him, and her. We were originally four unrelated circles, but just like the most familiar strangers, I wanted to talk to you, so I cautiously came out of my circle. But I found that you are all still in your own circle, and I don't know everything about you... In the end, I am still an outsider outside of your circle. If this youth is a funeral, then if I have to do it again, I will eventually be there in person. Because I didn't forget that there was a crying child behind me—her name was Destiny.
