My Senior Sister Is a Bit Fierce

Zheng Yue has a senior sister. She is aloof and beautiful, but towards Zheng Yue she is cold on the outside and hot on the inside. Later, Zheng Yue suddenly discovered that his senior sister, who had always been very kind to him, was secretly plotting to kill him. Zheng Yue fell into deep thought. He was wondering if the fact that he secretly helped his senior sister to deal with powerful enemies and had ulterior motives towards her was exposed? So he escaped on his own? Or should he wait until the child in the sister's belly is born and then run away with his own child? Or, counterattack first and then escape? This novel and its characters are purely fictitious.
