Wen Xuchun is a young village doctor in Qingshi Village, who values her life, is sharp-tongued, and only wants to live a peaceful life. Overnight, the imperial court's number one wanted criminal, covered in blood, hides in her medicine hut and immediately addresses her as his wife. She stabs him with a knife, and then, to clear herself of suspicion and claim the three thousand taels reward, turns back to carry the man out from the fire. Only then does she discover that she is standing in ten years ago. That old painting is a door. Every time it is opened, she returns to a segment of his past; every time she saves him, reality is rewritten once, and her vital energy and blood decrease by a fraction. This time, she will change this person's destiny.
