I Became A Slave to the Man I Abandoned
I recommend the Novel not the manga, the emperor character is different in my opinion, and the depth of the feelings of the 3 characters are just not convied, also the MC state of mind, for those who want the Dark psic stories reading the manga just don't cut it and even ruins it.
*Dark
*obsession
*force
*psychological
*character development
*ML regret
*complete end, no "happy ending" of abused and abuser together.
