Seven years ago, due to family changes, Lu Yuan chose to go to the north without saying goodbye in order not to hinder Zhao Yanyun who was preparing for the exam. Seven years later, a yellowed old photo (Zhao Yanyun's smiling face under the sycamore tree on Jiangcheng East Road) awakened the longing in his heart. He returned to Jiangcheng during the annual vacation and embarked on a journey to explore the old times.
He walked back to Wutong Road on Jiangcheng East Road, visited the old shops he had been with, and relived the details of Zhao Yanyun's past at the "Wanqing Coffee" on the corner. By a coincidence of fate, he unexpectedly reunited with Zhao Yanyun in the alley, and the words "Long time no see" ended the years of estrangement. From the frank confrontation in the teahouse to the resolution of old misunderstandings, the two gradually filled the gap of seven years through temptation and tug. Lu Yuan slowly approached with gentle companionship, and Zhao Yanyun opened her dusty heart with the encouragement of her best friend and mother. In the end, the two reconnected under the sycamore tree engraved with the mark of the past.
