Lin Xiaoman is a cultural relic restorer hiding in a studio in an old alley. He is so afraid of society that he only dares to say "leave it at the door and don't knock" when taking out food. But when it comes to repairing broken porcelain pieces and small wood carvings, his hands are steadier than those of a surgeon. Shen Zhou is the "cat owner" who runs a pet foster care center. He looks cold and talkative, but in fact he is a detail-oriented person who treats the ragdoll cat "Nian Gao" as his daughter. In order to repair the old stained glass wood carving left by his grandfather, he suddenly found Lin Xiaoman's studio.
