As tung leaves fall all over the streets, up-and-coming lawyer Lin Yu and freelance illustrator Su Ran accidentally meet in a cafe. A brush and an impromptu portrait make the two worlds intersect.
He is a logical defender of rights in court, but he removes all sharpness from his paintings; he is a creator who weaves warmth with color in the studio, but finds a stable harbor in his protection. They made ginger tea in the old studio on Wutong Lane, fed the orange cat, and drew illustrations of their daily life, thinking that this love could withstand all storms, but they did not expect that the heavy pressure from the wealthy family would come unexpectedly.
Lin's mother's malicious intention in her million-dollar check career suppressed the carefully planned engagement mistake, which cut the relationship between the two into pieces like sharp knives. Su Ran left home with despair, while Lin Yu searched the streets and alleys of Jiangcheng frantically for the pile of missing person notices in the printer. There was always a lamp waiting for his return in the studio of Wutong Lane.
A critical illness notice from the county hospital reunited the two people, who had been separated for three months, under a white wall. The shadow of congenital heart disease looms over the life-and-death gamble in the Shanghai operating room. Lin Yu uses the determination of "I won't give up on you even if I give up my family" to accompany Su Ran through the pain of pre-operative rejection and the suffering outside the operating room.
When Su Ran woke up, she saw Lin Yu's red bloodshot eyes; when they returned to Wutong Lane, the inscription "Ran Yu" on the inside of the ring reflected the sunset. It turns out that all suffering is foreshadowing and all separation is a test - he is his courage to fight against the world, and he is the exclusive antidote in his life. The wind in Wutong Lane will keep blowing, and their story will continue to warm in every fallen leaf and every painting.
