OK... Chapter 4 lists a foiled rape attempt, but chapter 6 doesn't list anything about attempted rape? Just because it is two girls doesn't mean that what Jun is doing to Misaki isn't rape. You can argue all you want about Misaki not pushing her away, but that is just a form of blaming the victim. She said "Stop" and "No" and even her internal thoughts were that it was disgusting. She is also quite a bit smaller than Jun and probably considerably weaker. There is no guarantee that she would be able to push her away if she tried.
Well, it's sexual assault, not rape. Jun with Tsubasa is statutory rape. But I don't know if we want to tag rape as we would in real life. All the age gap manga are as well. Unwanted kabedon, skirt flipping, could be considered sexual harassment. Based on how things normally get tagged, the judgement seems to be based on whether the characters themselves considered it as as such, and I think this makes sense.
