Freezing manga question.

I was wondering about a complaint I read about there being rape in this manga. I've more or less verified that there is one instance of this but before I might start reading this series I was wondering if anybody knew if there were multiple instances of such a thing in it. It's hard to google an answer when pairing the words "freezing" and "rape" together it seems.

It has been a while since I've read freezing so I'm not really sure. My overall take on it wasn't that it was a particularly "rapey" comic and the instance that I am thinking of was appropriately traumatizing in the story. But also taking in to account that it is by Im Dal Young(spelling?) and an ecchi manhwa with mature themes I wouldn't be surprised if there was mote than one.
