The Terminally Ill Villainess Goes on a Journey

"I want to take a train trip." I found myself possessing the body of Irene, a villainous duchess with a terminal illness. A second terminal diagnosis felt incredibly unfair! But there was nothing I could change now. To fulfill my unfulfilled dreams, I boarded the Ramier Express, a train that traverses the continent for a month. "So you're Duchess Hartmann. You were the one who saved my brother." "Why are you on this train?" Why are all the male leads starting to board? Not only are all four male leads on the train, but they're also showing interest in me. "I've decided to join you on your journey, Duchess Hartmann." ......No, I was planning on traveling alone?
