There are no years to grow up, and too many emotions have no clear boundaries. The beauty of love at first sight usually happens in the green years. The first time Yu Xin heard about Yu Yue was when she was too young to remember the story and didn't know Yu Yue's name. However, she knew that Yu Yue was a powerful person and thought that one day she would compete with Yu Yue. But the fate was too shallow. When she met Yu Yue many years later, Yu Xin had already fallen in love with someone else at first sight, while Yu Yue had vague feelings for the strange girl who often called him. When the girl on the phone fell out of love, Yu Yue told her, "Maybe you will know where you are going after you travel to the ends of the world, see the mountains and the sea, and taste all the flavors of the world." The girl did so, and knew that the place she wanted to go to was the rest of Yu Yue's life.
