An accident made Shen Yuan become the manager of the underground palace by mistake. He wanted to perform his duties well and stabilize order, but unexpectedly, the concern of his beloved wife Xu Nian turned into a series of ridiculous oolongs. From the piles of "materials" that almost caused "material oversupply" in the underground palace, to the obsession with protecting his husband that caused a big fight, Shen Yuan was at a loss to laugh or cry while cleaning up the mess, while feeling the deep love that spanned time and space. In the end, the two reached a tacit understanding in a unique way, using love and understanding to write a warm and funny alternative guardian story.
