I still have the burning question: What if she loses her virginity to Uni?
I do think that's a silly part of this series. The only thing that I could see making sense is that she's asexual and has no interest in sex. Beyond that.. if they are really in love with each other... sex is a natural course of things.
I bet there's gonna be some kind of time skip. Though actually, I'd kinda prefer it if they did a time skip in a couple chapters. Them being in the military currently and getting together currently would still be chaste and innocent. I wanna see them together as adults.
