• Background: The bustling yet alienated first-tier city "Xinghai City" has a Lujiazui-style financial center, fireworks alleys in the old city, and gray areas hidden behind office buildings.
• Protagonist:
◦ Lin Yan: 27 years old. He was once a promising architectural designer. He was banned from the industry due to an "accidental" design accident. He changed his career and opened an old object restoration studio. He has a cold personality but is hot on the outside, and is used to covering up the scars of the past with silence.
◦ Su Wan: 25 years old, a well-known food blogger in Xinghai City. On the surface, she is lively and cheerful, but in fact, she is burdened with family debt and her mother's serious illness. She walks through the streets of the city every day looking for "human fireworks", but she always feels lonely late at night.
