The Lonely and Brilliant God: The Passerby of Ghosts

Recently, I became obsessed with the new Korean drama "Goblin" and it was completely out of control, but I didn't meet anyone who could discuss the plot with me. In addition, I have too many brains, so I plan to open a pit and write something casually. Knowing what to write and not forcibly dismantling the official CP in the drama, I just want to add one more person in it and write the story in the ghost from another angle. Married, as a general or something, it's okay to have a fiancée.
