What my favourite event in manga etc. is? MC powering up? Nah. MC faceslapping everyone who mocked him or a triumphant return to the family? Close, but not quite. An established (!!!) MC-couple having a baby? HECK YESSS!
Oh nice! I mean their newlyweds who can still conceive and their pretty passionate about each other. So it was only a matter of time. As I say, sex doesn't have to happen on screen once a relationship vis established. Take, Clannad for instance.
