"Urban Heart Formula" tells a romantic love story that takes place in the bustling city of Shanghai. Barista Lu Xingchen is sunny and cheerful, believes in fate, and looks forward to "destined" love. Fashion editor Lin Yinuo is independent and confident. He believes that love must be won by oneself and scorns "fate".
An unexpected encounter and a cup of accidentally spilled coffee brought two people who had nothing in common together. The coffee stains formed a strange pattern on Lin Yinuo's white dress, which made Lu Xingchen, who believed in fate, even more convinced that the girl in front of him was the one he was destined to have.
However, Lin Yinuo disagreed with Lu Xingchen's enthusiasm and "destined" statement. Two people with very different personalities went from being dissatisfied with each other to gradually being attracted to each other in their daily interactions. During misunderstandings and tests, they gradually felt each other's sincerity.
When the "fate" of romanticism meets the "never believe" of rationalism, what kind of sparks will collide? When various accidents in life become the catalyst for love, how can they solve their "urban heartbeat equation"?
