Nana lives with her grandmother and her grandmother's remarried partner. Her kind grandmother always spoils Nana like she is still a little girl and doesn't treat her as a woman. One day, her grandmother tells her to wash her step-grandfather's back while he's taking a bath... Nana is being ○○ed by her step-grandfather and can't consult anyone about it... The only option left for her is to become his plaything in this hell of harassment under the same roof.
