Forcing a Concubine into Marriage

A new woman in the 21st century suddenly became a young lady from a general's family in another world due to a car accident. Fortunately, she lived a comfortable life and was loved by her family, which was not bad. But I don't want to be forced into marriage. As a woman in the new era, she will definitely resist to the end, but she has the leverage of her old man, so she has to marry even if she doesn't want to!
