@LightningLeaf Bit of a necro post but in volume 1 Char clearly says (monologs to himself anyways) that he has never considered being intimate with Lam because he didn't want to risk having any biological children when he knows how horribly his own childhood went strictly because the families former leader repeatedly tried to have him killed so their son could take over.
Now, this was of course before he realized Lam was hot magic jesus with a bundle of sociopathic apostles who are all trying to get into her pants with various levels of ignoring consent. Even when he does start to think he's actually attracted to her he recognizes that she hasn't voiced the same thing and he isn't a fucking rapist (Which, much to my disappointment) seems to be a rare quality in this world.
