Is My Best Friend's Cousin Really That Fierce? He Lulls Me to Sleep at Night

[Sweet romance, love after marriage, an utterly lovestruck hero who gives her the upper hand] At twenty-four, Su Ling unexpectedly discovers that she was switched at birth. Her older sister, Su Qingyue, is the very person who once saved her in her youth, like a ray of light. She’s thrilled to return to her family. But… Her sister is about to get married as soon as she returns. Her world is ending! (>_<) The good news: when the marriage arrangements are switched back, she’ll be marrying alongside her sister. The bad news: her groom is the second eldest son in the family of her best friend, Fu Xi! “My second cousin is a devil.” “My second cousin is basically a robot.” She’s been traumatized by those rumors for years. For the sake of her beloved sister, the trembling little sis agrees to marry him! - The year the family arranged her engagement to Fu Shizhou, He Huanyu had met him only once. The man was so rigid and dull that he drove her up the wall. She was leaving a ten-billion-yuan household to return to a hundred-billion-yuan one, and she changed her engagement to Su Ling’s without hesitation. She chose the romantic, charming campus heartthrob instead. He Huanyu would always choose the best, and she would always be the envy of everyone. But when she saw the man holding hands with Su Ling, gently brushing crumbs from the corner of his wife’s mouth, she was utterly stunned. Wasn’t he supposed to be boring and aloof? - Fu Xi: “Bro, did you change your style?” Fu Shizhou: “How did you know I got married?” Fu Xi: “…” Before marriage, Fu Shizhou was a handsome statue of a man, doing nothing but working. After marriage… He had an insatiable appetite for her and her alone. Fu Shizhou: He had never believed in gods or Buddha, but one thing finally shook his conviction. In the end, he got what he wanted. Su Ling: Marriage is like a maze. Finding little clues that he likes her, one by one. This marriage is quite intriguing. 【It began with love at first sight. A calculating, sharp-tongued charmer × a sweet-talking, adorable host】
