I didn't read it that way. It's pretty obvious that he's humoring her. He's never given any sign of seeing her as a woman.I really enjoyed this, but that sort of open-ended, ambiguous 'did he say yes?' relationship between the MC and the adult mangaka really sours the ending for me
maybe I'm just letting the oneshot (chapter 11.5) impact this work too much, since the mangaka definitely seemed to entertain a reciprocal relationship more in that than this, but I still felt like the dude was entertaining the relationship more than humouring her in this serialised work.I didn't read it that way.

She's 12. By the time he moves away and then moves back, she'll be a completely different person. He knows that, she doesn't. He doesn't want to hurt her feelings because he cares for her (in a non-romantic way), so it puts him in an awkward spot.
So the best thing to do is a kiss on the forehead and a "we'll see."
