This is fate, and the fate is so wonderful. Maybe it was Enlang's decision to go back to China to study, maybe it was the beam of sunshine when Enci saw Ruilang, maybe it was the moment Qiao An saw "Warm". I don't know who will accompany whom on the journey of life, and I don't know when the stop will be and where the end will be. But as long as you face the sun, even if there are tears, they will be dried, and the shallow traces left behind are not sadness, but the footprints of growth. This is a story about acquaintance, love, waiting, and happiness. It is warm and touching, but also contains humorous scenes. To commemorate our colorful youth, I hope everyone will support us
