Irgendwann werden wir uns alles erzählen

A dirty and old(ish), somewhat unattractive brute starts advancing on the local 17 year old beauty. Unfortunately for everybody, he gives off a major rapey vibe. Their first meeting is literally him groping her without consent.

Since her boyfriend is very goofy, she eventually gives in to the brute and allows him to take her very roughly and a borderline sexually abusive affair ensues.

It's a German movie, so this counts as a romantic comedy.

The lack of diversity is fine. This is set in early 90's East Germany and people of colour and the disabled obviously hadn't been invented yet.

The cinematographer needs a big raise though.
