Okay, for one - maybe it's just me or the games I play here, but man, if I never ever have to see a fairy in a porn game again, it'd still be way too soon. So over it. Same as dream sequences, aka. the crutch of writing anything.
Second, either Meiko needs to be a bit younger, or the MC a bit older. As it stands, it's 39 to 23. So he was ~16 when she was born? That's not exactly the age where you look at babies/children around you and feel all fatherly about them, so his hesitation to do anything when naked Meiko basically goes 'RAVISH ME!' is even more hilariously misplaced and stupid than all the other hesitation we've seen so far. And boy howdy have we seen a lot of that already...
I mean, just think about the situation for a hot minute. Meiko's whole thing, her whole 1 dimensional character arc so far is 'extremely shy girl' (well, and 'token asian', but nevermind that). She's shy to the point of anxiety.
And yet in the relationship dynamic between her and the MC, SHE is the one to move forward.
So what does that tell you about our MC?
