father daughter incest

12-year-old Mitsuko is regularly locked in a cello and forced to watch her abusive parents perform a series of intimate acts. When her mother kills herself, his father rapes her and she ends up restricted to a wheelchair following a failed suicide attempt. Later, it begins to appear that the preceding events were nothing more than the details of a new novel by reclusive, wheelchair-bound author Taeko. The arrival of her new assistant and admirer Yuji will challenge that possibility in the most surprising way.
