hey! Livi is not that young. He's just short for his age. Nike is not that old too so they don't have that much age difference. And Fortis won't touch Luna until she's of proper age so I think it's ok.
Maybe the author like to ship younger people and older people....
I think it's shotacon because Livi is 12 y.o while Nike is 17 y.o....
But in the anime he was 15 y.o maybe because he is too young and so they decide to adjust his age or something like that~ ╮(￣へ￣)╭
12 y.o kids these days fall in love and have girlfriends (but usually with girls their age). Five year age difference is nothing when you get older. But now it does stay within shota boundaries. Just to be fair, royalties and ancient cultures have early marriages all the time. I know chinese people have marriage commitments even before they're born. Some tribes marry off the girls as soon as *cough*sorry if I'm rude* their period comes. For neighboring countries it's politically essential to keep royal blood ties linked so things like being cousins or being too young, etc are sometimes ignored. It's logical for Livi to crush on Nike or have puppy love for her. I also felt a little uncomfortable with recent developments where Nike kiss Livi or she feels nervous about him. I mean, it's ok to kiss since they're already married and have affection between them. But I think she's getting awareness of Livi in sexual tones. Hold your horses girl! Even if you've already become a full fledged woman, your dear husband is still shorter than you. And I think it's easier for you to develop such thoughts when you live in a society which encourages the idea, not forbids it. I mean our lives would be a lot different if we grew up with parents who are pirates, or swindlers, etc. Some say you make your own decisions but your life experience and environment have direct, indirect or opposite effects on them.
It's already SHOTACON and now LOLICON???!
