My Younger, Twisted, Brooding Puppy Cries and Calls Me Big Sis, Begging Me to Discipline Him

[Reborn + dark, obsessive madman + fiercely possessive + younger man scheming to rise to the top + spend-money tycoon System] When Pei Zhixia was eight, Pei Yanchen took the homeless girl in. From then on, he became her whole world. Longing for a home, she was obedient and well-behaved. When she was nineteen, he asked her to seduce the fiancé of the woman he loved, promising to divorce that woman and bring Pei Zhixia home. She married him. But he broke his promise and never brought her home, not even before she died. In the end, it was her husband, who had only married her in name, who avenged her and died for her. - The first thing Li Siheng did after coming of age was use every means at his disposal to claim Pei Zhixia. Only after she was reborn did she realize he had two faces. In public, he was so abstinent he seemed like a monk, earning him the nickname “the Buddha of Beijing’s elite circle.” In private, he watched her every move, even climbing into her bed in the middle of the night… and secretly keeping anything that carried her scent. Yet this man, who was completely unhinged at heart, cared about her more than anyone in the world. In this life, she takes the initiative to enter his world, forcing him to show her his dark, obsessive, unhinged true self. Pei Yanchen? What a piece of trash. She only wants Li Siheng! But what’s with this tycoon System that picked the wrong person? It insists she complete missions, spending money on other people so it can refund the money for her to spend on Li Siheng. If she slacks off, it shocks her. “Big sister, here, here… Is this all okay?” “Big sister, the Li family doesn’t believe in divorce or leaving a wife to live like a widow.” “Big sister, spending money on me is only natural. Are you spending it on other men because I haven’t spent enough on you?”
