Xu Xingyang, the "Iceberg" of the Law School, and Jiang Qiqi, the "Little Sun" of the Philosophy Department, met unexpectedly. One builds barriers with indifference, and the other dispels the haze with enthusiasm. The two completely different people are repeatedly pulled between each other in the scorching sun of military training, the stage of the welcome party, and the corridor on rainy nights. Xu Xingyang buried his love deeply due to family trauma, and his clumsy approach always turned into a hurtful thorn; Jiang Qiqi wandered in misunderstandings and temptations, thinking that he was a "mobile refrigerator" that was rejected thousands of miles away. From the fog and rain in London to the sycamore trees in a small town in the south of the Yangtze River, three years have not been able to erase the imprint in my heart. When Xu Xingyang returned with the idea of "Shiguang" pub and built a new nest next to the former bookstore, the dusty past surged in the steaming heat of the hot pot. The drunken babble, the avoidance when they meet again, and the secrets buried under the frozen soil all tell the story of the unspoken love. This is a story about the collision of frozen souls and burning sincerity, exploring the essence of first love amidst misunderstandings and misses. When the sign of "picking up light" lights up, can those seeds buried in time break out in the twin resonance? The wound of first love has never scabbed over, but it is settling over time, waiting for a belated spring rain to water a reunion that spans time.
