At the moment, the four main characters all want the main-main character to love them. Which he sees no reason not to, really. I suppose there could be some jealousy of who he really loves or who gets to "have" him, but I don't think this particular world works quite like that.

Hm. Or maybe it does.

On the other hand, that likely means I need a fifth main character for my main-main character to be with in the end.

Hm. That might actually work.
