Jin Yu was once a handsome young man from an aristocratic family, but due to a conspiracy, he became a lonely stranger in the world. He was burdened with a blood feud and had a cold and distant temperament. Only a glimmer of light deep in the old palace was an obsession that was still lingering in his heart. Yuyao was born in a world of fireworks, with an unknown past hidden between her eyebrows. She is gentle but sharp. She accidentally breaks into Jinyu's world and becomes his salvation in the gloomy years. The two passed through time, and the bricks and tiles of the old palace were engraved with their encounters and partings. Conspiracies and truths were intertwined, and love, hate and debt were entangled. When the dusty past is revealed, can Jin Yu let go of her hatred, and can Yu Yao face up to her original intention? This old palace will eventually witness whether they can escape their fate, or reconcile with the past, and spend the rest of their lives together.
