I'm not trying to kill you.” On the day of Young Master Fu's engagement banquet, I stole his fiancée away, and my older sister stole my first kiss. I swear, she made the first move. It had nothing to do with me. I just went along with it and spent the night in intimate contact with her, that's all. “Brother Shaoyuan, don't be angry. My sister didn't mean to. Maybe seeing me made her lose control.” I didn't expect you to be so stubborn, still insisting on marrying her. I had no choice but to resort to a few tricks. I never expected my sister to love me so much. She took advantage of my half-hearted resistance, overpowered me, and claimed my body. “Brother Shaoyuan, it was my first time.” My sister said it was just for fun and not to take it seriously. But, sis, when you provoke a yandere, do you really think you can walk away unscathed? Whoever dares to marry you, I'll steal you away from him. I'll make you my wife, keep you craving me night and day, and leave a mark that belongs only to us. You're so wicked~ I've made my intentions crystal clear, and you still won't come tease me. But that's all right. This little brother has his own way of getting you to bite. “Brother Shaoyuan, my sister can only be my wife!” “Stealing her away is my destiny as her little brother.” [Content warnings: Sweet and angsty, with a realistic bent. The male lead is inexperienced, while the female lead has had previous relationships. Don't read if you can't accept the heroine having dated before. The heroine comes from an ordinary family and has a tragic background, but is resilient to the core. The male lead is an idle young master from a powerful family and a VIP at the city's pleasure palaces. The male lead is involved with women in the early chapters. His family raised him with extreme severity, and he suffered inhuman abuse and a tragic childhood. This is a mutually redemptive romance between two people who are both hopeless romantics.
