The Layabout Heiress

The family's heiress was sent to the mountains to learn skills. After 15 years, this is her first time going down. Everyone's waiting for her to show her skills. But instead, she said, "Comes the music and dance together." It got the whole place up. Their enemy mocked. Her family sighed and her fiancé tried to break off the engagement. She didn't care at all and just had fun with her four brothers. Until the day their enemy appeared, she stood straight and proud. People can slack off, but they can't be truly incompetent! I am already unbeatable!
