Have you ever read a novel whose ending surprised you?

The ending of the novel I once read," I Transmigrated to Become a Banshee's Master, the Great Villain," was quite unexpected. In the original novel, the female channel's villain master was regarded as a thorn in the side by the female protagonist and was eventually destroyed. However, in this novel, Xiao Yuhan successfully escaped an extremely bad fate with the help of the system, which made people feel unexpectedly satisfied. I hope you like my recommendation.
