Ancient tanner Lin Chunsheng transmigrates into a notorious scumbag husband, and upon waking up is asked for a divorce by his wife Zhou Jinglan. Learning of the original owner's evil deeds of forcing marriage and stealing money, he promises to let go after one year, starting from repairing tool kits and making leather buttons using traditional leathercraft, carving out a career amidst cold glances and doubts. Facing Chen Zhiming's instigation, reporting, and leather-destroying conspiracy, he breaks the deadlock with strength, recreates the oil-wax vegetable-tanned leather craft, and gets hired as a technical consultant in the province. Zhou Jinglan gradually falls for him, but he ends the mistaken marriage as promised and heads to the provincial capital alone. She transfers there, proving her sincerity with work and actions. The two join hands to save leather materials in heavy rain, welcoming a breakthrough in their careers and deciding to start over from dating.
