Tatsu, no need for spoilers, really, what is this based upon ? original work, right ?
we can discuss our opinions about that and what we want freely,
and I'm with kamineko as well, i don't want any romance around Ohana too soon, if any should be, it hsould be when things around her allow for it, first of all, we get to know some new characters and we want development, we know a bit about everyone so far, nothing much, we don't know if Ko is suited for Ohana at all, what if Ko only wants her for himself, and now he plans on this voyage only to make sure she doesn't hook up with anyone more worthy of her ? if she finds someone who makes her feel comfortable around with and it's not Ko, i'll be fine with it, we also don't know anything about Ko yet, we only know he was aiming to be her boyfriend all the time, if that is correct he wasn't a good friend at all, and he might be the last person suited to be near her, if the creators of the anime have something planned for Ohana, I will wait patiently, cuz it's worth the wait.
