The memories left in those youthful years wandering around, and at a certain moment, a certain place suddenly appeared in front of me. Those young days that have passed by vigorously, those people scattered in the end of the world, a faint smile floats on the corners of the mouth unconsciously. If it weren't for those people, Su Momo might be like those children who strive for their dreams, following the so-called track of success and fame, walking a path that may not belong to them. However, such an unexpected encounter has become an indelible trace in life. She silently said, "I don't regret it. Even if we pass by each other, there is destined beauty. What's more, I didn't just meet..." Lu Xiao said, "If it weren't for me, you might still be that good boy, and you would still be in a world without fighting against the world. Am I right? Or wrong?" Qin Tao said, "If there is a future, and there is eternity, I would like to be the one who stays with you on the banks of Walden Pond." All kinds of details outline a delicate song in youth.
