There are some ridiculous intepretation about the story here that I just cringe at. Holy crap. The way I see it, the main lead is just some lonely man trying to help out a stranger that's recovering from some traumatic shit. I mean, he wasn't really coming on to her nor does he desire her explicitly.
He probably knows that they can't live like this forever and will have to separate at some point. And the gyaru will probably say something to that effect.
Idk, we'll find out next month.
