Rebirth and Living as the Protagonist in Your Own Heart

Reborn full of hatred, the only hope in this life is to experience and maximize my role as a supporting role. I don't want to change my sister's ending, I just want her to be intact! Hearing the person who let him down in his previous life say that he only loves himself in this life, Cheng Wang, who once thought he hated him, even said that he already admired him, and his sister who used to be devoted to him was even more unscrupulous... Lying in a pool of blood, I suddenly felt nostalgic for the days before my rebirth. Wouldn't it make me feel better if I didn't know the truth?
