iirc that's just borderline porn and ended up in lesbian sex or something. Apparently it was the first time the actors engaged in something like that deep in the film too but I think they did alright considering that afaik, they are straight. Story wise was nyeh. Something interesting to note is that the amazon descriptions of each volume kinda tells you what happens in the predecessor novel so yeah, I can already tell that it's way different to the live action.
