If You Don’t Behave, I’ll Lock You Up: My Yandere Younger Brother’s Forced Love

The only thing that can cure a lunatic is another lunatic in this world. “Big Sis, don’t you want me anymore?” It’s fine. Big Sis ran away, she didn’t die. 【System + love at first sight + devoted simp + younger man + both leads’ first relationship】 Su Qian picked up a System by the side of the road. Its first mission was to win over the eldest young master of the Gu family. What she didn’t know was that the beautiful, bewitching boy trailing behind the Gu family’s eldest had set his sights on her. He always seemed to be smiling, but who knew what schemes he was plotting... With the Gu family’s eldest master outside the door, the boy cornered Su Qian inside and kissed her again and again. “Stop thinking about Big Brother. Can’t you just look at me?” When the abstinent young man everyone knew finally dropped the act, all he did was go crazy in her ear, over and over. “What I want is mine for life.” “Is Big Brother really that good-looking? Should I break his legs?” The boy asked her with complete seriousness, “Big Sis, what kind of lock do you like? Hmm?” But he could never bring himself to truly hurt her. He could only cry and beg, “Big Sis, don’t leave me.” When Big Sis got mad and scolded him, the little wolf cub immediately behaved. Big Sis loves him. Why else wouldn’t she scold anyone else?
