Thanks for saying so.
As for the lewd, I've said this a bunch on discord, but I pretty much developed the first version of UA in a complete bubble. I had no if people would even play it, let alone enjoy it. I felt like if I didn't include some sort of lewd scene, I'd be hamstringing whatever potential the game may have had.
So, yeah. You're not wrong. It's out of place, and while I think it would probably be fine down the road for these characters, it doesn't make a whole lot of sense where it's at. I'll probably remove it in some future update after I've added more sexual content, but for now it stays since there's really not much else on that front at the moment. And aside from how it comes out of nowhere, most of the feedback on it has been otherwise positive.
