The Endless Tricks of the Yandere Junior Sister

[Fantasy/single heroine/slightly yandere/double clean/system/daily more] Wu Feiyu was originally a migrant worker, but she encountered an accident on her way home from get off work that day... After waking up, I found that I had turned into a baby. Listening to the chaotic noises around me, I felt that I had been reincarnated in another world in this life. And what the hell is memory? Twelve years later, Wu Feiyu followed her master and met her junior sister Li Xinmeng "Hello, little... Junior sister, this is our first time meeting you. I am your senior brother, and my name is Wu Feiyu." "Hello... Hello, senior brother... My name is Li Xinmeng." Not long after, Wu Feiyu felt suffocated when she saw Li Xinmeng forcing herself into a corner. Why did her junior sister become like this? She kept pushing in, asking why Wu Feiyu wanted to find other women. Is she not good enough, or is her swordsmanship poor? … It was not until later that Li Xinmeng tied their hands with a gray iron chain. "Senior brother, I like you, let's get married!" "Poof" Have you ever seen anyone get married like this? The groom is locked by the bride? And we haven't even become Taoist partners yet, so you just skipped this step, right? … Looking at the dim room around him and Li Xinmeng sleeping peacefully in his arms, Wu Feiyu felt helpless and relieved. His hands and feet were bound by chains of chaos, unable to move at all... But he loves Li Xinmeng, so let her be.
