Transfer student Wen Li was once deeply trapped in the emotional and mental haze caused by her ex-boyfriend Lu Zhixing, who was obsessed with paranoia and repeatedly disrupted her campus life. He Ran, a young man from the Department of Architecture, seems to be unruly, but in fact he has been secretly in love with Wen for several years. He secretly writes down all her preferences and always steps forward when she is in trouble: he stops Lu's entanglement in public, warms her milk and prepares stomach medicine, hands her an umbrella on rainy days, and stands guard outside the classroom late at night to protect her safety.
He Ran hides his identity as the heir of the He family in northern Beijing, but due to a break with his father's ideals, he works odd jobs alone in Nancheng, lives in a dilapidated rental house, and pursues his architectural ideals with his hands. Lu Zhixing was jealous and kept spreading rumors to smear the two of them. He Ran did not hesitate to use resources to fight back head-on. Family persecution and industrial suppression followed one after another. He Ran did not want to drag down Wen Li and disappeared for a time. However, Wen went to Beijing alone to face He's father's financial inducement and use his professional legal knowledge to tear apart the other party's business conspiracy.
The two worked together to resist the shackles of the He family and resolve Lu Zhixing's malicious intentions. He Ran founded Liming Architectural Firm named after Wen Li, and Wen Li grew into a top lawyer. From the starry sky on the rooftop of Nancheng to the hand-carved wooden cabin on the top of the mountain in northern Beijing, they overcame the estrangement and hardships and became each other's dawn. In the end, they stayed together and ushered in a stable and bright rest of their lives.
