@eunoiavity Eh. I agree, but only to a point. While I do think anyone of any age could fall in love with anyone else of any age, I do think there is a point where the older party needs to go "No, they are too young for this.". Granted there are always exceptions, I've known people much younger than me that were more mentally mature than I was.
I've seen many age gaps relationships too, hell I even have a soft spot for them. While I do think there is an age range where someone is too young to be able to be in a healthy relationship, once you reach a certain point mentally I don't think it matters anymore. Who cares if your lover is twice your age so long as you are both happy. I've met enough adults who are less mature than high schoolers to make me jaded to the whole "you keep getting more mature as you get older" thing.
I don't put much stock in the bible so whether it lays down age of consent laws doesn't mean anything to me. I do think that said laws tend to be a bit arbitrary and will never fit all situations.
While I think "who cares about the law? us living beings needs love." is a great ideal, reality is often a bitch. If you don't care about the law then you risk your entire life potentially being destroyed. Anime/manga always ignore or sugarcoat this, which I think is fine. I don't read this stuff for it's realism, I read it to take a break from realism. Koi Kaze was probably the most realistically portrayed "taboo romance" I've ever seen, it also had the double whammy of sibling incest and and age gap. Never felt so much visceral tension watching something until I saw this show.
At the end of the day everyone's life is theirs to do with as they wish, and as long as you are not hurting your partner then whatever. Not my place to stick my nose into it even if I don't condone or agree with it.
More topically I'd say people making a fuss over Hal liking her are being dumb. I doubt there is any physical attraction felt, though there is almost certainly mental attraction. Considering she acts like someone 3 times her age I'd say you can't really fault him.
Also sorry for the wall of text, just started typing and rambled more than I meant to.
