Lin Xiaoman worked hard in an advertising agency for three years, but was rejected in public at the proposal meeting because Party A said he was "not young enough." When she collapsed, she met Shen Xinghe who was doing latte art in the cafe next door. The barista, who always wore a sunflower badge on his apron, gently opened her tight guard with a cup of latte with a starry sky pattern. From then on, he would always deliver stomach-warming sweet soup late at night when she was working overtime. On frustrated rainy days, he would hold an umbrella and wait downstairs of the company, curing her fatigue with improvised special coffee blends. When Lin Xiaoman finally won a big order with her innovative plan, she discovered that Shen Xinghe was actually the hidden owner of a coffee chain, silently providing resource support for her advertising planning. In the fast-paced urban jungle, the two of them went from stranger to familiarity, from heartbeat to two-way love. With their delicate tenderness and firm protection, they wrote a romantic chapter that belongs to ordinary people - it turns out that the best love is when you and I happen to become each other's harbor in the crowded crowd.
