The fake daughter framed the real daughter and sent her to a lunatic asylum. She was imprisoned for half a year. After she came out, the real daughter became extremely well-behaved. After returning home, she found that the fake daughter's sister was better at acting than before.

She pretended to be a well-behaved and normal person, but in fact she was crazy.
