Book Transmigration: Saving the Sickly Villain in Another World

This book is pretty good If you can't read sadistic stories, you don't have to read them. This book is a bit sadistic. The male protagonist abuses the female protagonist Of course the male protagonist likes the female protagonist, this is undeniable Then emm, let me think about the plot. The female protagonist is the male protagonist who traveled through the book and seemed to be reborn (maybe I remember the plot wrong). The female protagonist is the male protagonist's master. What I remember most clearly is that the male protagonist said to me, "Are you so lacking in love?" The male protagonist was quite miserable when he was a child, and so was the female protagonist (I forgot some about the female protagonist) Later in Volume 2, the heroine goes back in time, but in real life, only one day has passed. The hero first died in love, and then also went to the heroine's world. Okay, I can't remember the plot clearly, some of it may be confusing, um, no more
