What is your least favourite Visual novel trope/convention?

This may be a bit trite but I'm curious on aspects of the medium that you guys dislike for whatever reason. Personally my least favourite VN "trope" is when the otherwise normal mc explicitly turns into a beast during Hscenes and treats the Heroine VERY roughly to where everything just goes back to normal afterwards (namely some scenes during FSN like the UBW Hscene), I am not really fond of them since it makes the MC quite unlikeable during it and the scene comes across as trying to hard and a bother to sit through.
