First of all, Minji cried because Yuna was mad at her and she didn't want her to be mad, that's literally what she says when she first started crying and mentioned throughout. Second Minji wanted to take things slower, but she never told her that she didn't want to have s** with her during or told her to stop at any point because she was the one to pull Yuna in for a kiss and initiate everything and from this chapter alone we can see that she wasn't disturbed or shaken on what happened so you calling it ra** is dumb and you're only taking lines out of context to prove your point which falls short when looking how things turned out in this chapter where Minji is blushing and wanting Yuna to stay.
So it's not pretty privilege when you're just wrong because it's not ra**. Minji wouldn't be so calm or willing to be around Yuna if it was and her reaction afterward would have been very different in this chapter as well. So you can go kindly fu** off
