I have to admit, in terms of gameplay, I didn't like this hangout at all. It didn't really have anything to it, just touch M here, here, and here, then touch J here, here, and here too. Write on an arm, touch some objects...
At least in the other hangouts (I think) you get some form of meaningful dialogue. I might be tainting my memory, but I don't think there was much said in this one.
In terms of actually hanging out, taking away the gameplay, it kind of felt like the girls were chilling, MC tries to get their attention, but they're happy doing what they're doing, so he gets up and buggers off.
