Pluto Betrothed: the Ghost King Welcomes His Bride

I once had a dream. In the dream, a group of ghosts with strange postures came to pick up a coffin. I was wearing a black and red wedding robe and a black hijab. I was lying in the coffin, and a blood-stained coffin nail was slowly driven from the center of my eyebrow... I thought it was a dream, until one day, because of a legend, I was going to devote myself to the entire Yin and Yang family to marry the Lord of the Underworld, the Lord of Hell. Just like in the dream, a group of little ghosts came to welcome the bride carrying a coffin... My originally peaceful life was turned upside down by the presence of the Lord of Hell and the resentful spirits every night. In addition, I had to find nine coffins containing my two souls and seven souls. It was said that in this way I could find the sealed memories of my previous life. What was my previous life like? I don't know, I can only look for my nine coffins in this dark night full of resentful spirits...
