The Ghost King's Seven Nights Beloved Concubine

The most bizarre time travel in history is when you wake up and find yourself lying in a gorgeous coffin. Not only that, there was a "dead man" lying next to him. The most bloody encounter in history is getting married in a coffin in a daze. Not only that, the ghost king husband who had been dead for seven days miraculously came to life and doted on her to heaven from then on. But after seven nights of being pampered, it turned out that all of this was just a huge conspiracy. She lost her heart and will never recover.
