My Possession Became a Ghost Story

I transmigrated into a romance fantasy novel.The problem? I woke up inside a coffin on the original owners funeral day.Worse, Ive read way too many romance fantasy novels to figure out which story this is. My family is cold and heartless, and the maids tremble whenever they see me At this rate, I must have possessed the villainess.Fine. With all my rofan experience, the first thing I need to do is escape the villainess route!While searching for a way out, I discovered a strange symbol.Whats this?[How to Summon ]A summoning circle to call a spirit? A dragon? Perfect. A villainess should at least have the power to protect herself.Meow.But instead of a spirit or a dragon, why was I chosen by a three-eyed, leopard-spotted cheese cat?!Well, whatever. Its adorable, so I dont mind.There is a monster living in the Rohanson Counts estate.A monster wearing the skin of the late Lady Evangeline.A heroine who believes the world is just a romance fantasy novel And the people around her, forced to experience horror stories because of her.
