I recommend the ancient romance novel "Xi Dang Niang: This Husband Is Going to Be Cold". The female lead transmigrated to a woman who had died tragically. After she survived with her child, she started an emotional entanglement with the male supporting character. The male protagonist was not the child's biological father and initially opposed the existence of the female protagonist's child. However, as their relationship warmed up, he was willing to raise the child with the female protagonist. I hope you like my recommendation, Mwah ~
