Let me guess. This is a home invasion story. The gold badged Reimu has just let the wild bawiza into the house and they refreshed. Now Reimu is going to protest that her paramour and the babies are VERY easy....
I have my doubts about calling this one FF, specially if there will be a potential follow up later with the typical "Pet + Stray - Owner's Permission" scenario.
I would give it the benefit of doubt until we got 1 or 2 more pics of the author that aren't follow up.

It's called being genre savvy Starshine, and it's not looking for reasons, but suspecting possibility of this not being FF out of being too similar to some non FF scenarios, and if a follow up pic proves it. Better be safe than sorry, I do recall that with "True Happiness" even if people knew darn well kiriraita, they weren't savvy enough and got a serious dissapointment because the story wasn't FF.
I still could be wrong, but we need somethign to prove or dissaprove the situation, like an artist comment, translation or a follow up pic.
