Can something like this even happen?

Your delima all started when you read a novel before going to sleep and the next day you woke up besides someone else in an extravagant room, one aristocrats would have used in behind your century.

Later after coming to a realisation, you did transmigated to the novel you were reading, a sweet romance between the Grand Duke and the poor Baroness. But you, you were not the baroness or anyone related to the plot at all. Just the Grand Duke's fiancé who gets killed in 2 months time, who had no effect to the world or its people.

"So you wish to annul our engagement, is that it? Is that why you have caused trouble you normally wouldn't have?"

Trying to save your life from this tangled mess, what you thought was a good option seems to be on the verge of rejection.
