She saved his life, but the crazy man locked her up. She was a mermaid who was inexperienced and had no understanding of feelings. He was the second master Si who was feared by the world in the north. She went crazy and wanted to escape, but was locked in bed by the man and had fun every night. She cried and begged, "Woo woo, I didn't mess with you, I just went ashore to find a partner, I will go back when I find one" The man was domineering and arrogant when he heard it, "Good girl, you are already mine, your partner is me" "You are mine from head to toe, but no one dares to be your partner" —— Later, she ran out, thinking that she would finally escape from the clutches of that madman and gain freedom. Unexpectedly, she lost her memory, and the madman fell from the sky and tricked him into thinking that he was her husband. They had been married for three years. "Darling, you won't leave me, right?" The man looked at her pitifully. Nan Mianmian's heart softened and she nodded ignorantly - he was mad and cruel, but he was willing to bend down for a fish. Only that fish dared to scold Si Ye, and only she scolded Si Ye. Si Ye didn't talk back. When the little darling cried out of grievance while being scolded, he had to squat in front of her and wipe away her tears. "Mianmian, after scolding me, you have to stay with me well." Mianmian can drop pearls of various colors! Main characters: Nan Mianmian, Qin Ye
