I recommend "Strong Lock Marriage: A Hot Wife Is Not Very Good" to you. This is a modern romance novel about wealthy families. The male protagonist, Huo Shengting, became a sinner because of an accident and hated Su Nianqi to the core. When they met by chance five years later, Su Nianqi became his prey. Su Nianqi had no choice but to escape in order to save her son. In the end, she and her son really died, but her heart was transplanted to Huo Shengting, who later went crazy. I hope you like my recommendation. Muah ~
