Hello! Please help me find this book. I'm not sure if it's in novelupdates or in wattpad. But I remember an arc or the novel where MC entered a body where the original is sick. His sister is pretty crazy, beating him up when their parents are away or when he is alone. No one found out until they saw him nearing his last breathe, his arm is dislocated and had a very high fever. They found out the sister's real face and told her to leave their house. And the crazy sister is also in love with the ML, which is a their family friend or something. ML visits Mc from time to time.
