This is where we veer into NTR territory right? He 'goes home alone' and then she is determined to do her best, shows up at Director-san's apartment for one of her famous 'dates'... except he's got different ideas and subjects her to several days of intense sex and orgasms until she's totally broken. Kazuya sees less and less of her leading up to the movie's debut, which the Grandmas and Kazuya and the whole rest of the family are eagerly attending and... it's just a 2-hour video of Chizuru getting turned into a cum dump
