The Legitimate Heir

She was a special agent with the Second Intelligence Division of a military region, but after an accident during an operation, she transmigrated into the sprawling mansion of an ancient family and became a young lady. With this frail body, all skinny arms and legs, that needs a breather after a few words, and all these maddening rules, how is anyone supposed to live?

She refused to accept it. She swore to take back everything that belonged to her and head straight for a happy life!
