There are many equally bad upbringing or worse if I were to compare to novels but in webtoons... I think it would be Death is the Only Ending for the Villain (this is based on the torment they experienced during their upbringing (￣∇￣")) Another one could be How to Protect the Heroine's Older Brother.
yes I also seen that and the mc of that novel only witnessed the death of her brother which isn't nearly as bad as suffering for hundreds for year of torment also the psychical and emotional pain of when she was alive as a child. neglect is the worst thing you can do to a person and thus creating a emotionless monster
That's why I only mentioned the upbringing. I didn't include the time she suffered when she turned into a sword. I don't think the other stories have a webtoon that include long time suffering. In the Heroine's Older Brother, she was originally an ordinary person, her mom being weak and her brother dying in front of her would cause her to break down. She had to change herself to a heartless monster just to survive. I would say that was equally bad or worse upbringing. (⌒▽⌒)
sometimes I wish there was audio just piano playing for the right moods. also Charlize's upbringing is far worse than any other character prove me wrong
