He is a rising star in the world of ancient book restoration, and he is also the clean and well-behaved apprentice Wen Xuyan in her eyes. She is the top restorer in the industry, the cold and distant Su Yanci. A rainy night apprenticeship closely connected the fate of the two. He passes hand warmers, makes ginger tea, and wards off rotten peach blossoms with meticulous attention to detail; he discerns paper like a god and searches for ancient books like a bag. He is extremely talented. Su Yanci only regarded his apprentice as a piece of rough jade, but he didn't know that under those clear eyes, he hid his true nature of "white and black" with deep foresight. When her father's unjust case that had been buried for ten years was quietly revealed, and when the boundaries between master and apprentice were blurred in the day-to-day interactions, she was shocked to realize that this carefully designed "apprenticeship" from beginning to end was just to get closer to her. Beside the inkstone, we express our sincere feelings and watch how Master Gao Leng is attacked by his "good disciple" step by step. They work together to protect ancient books and each other. Thing!
