I'm a little late to the party and I have mixed feelings.
Very mixed feelings.
Sleeping with a nonverbal severely ptsd vulnerable nonfunctional person under your care isn't helping them. Did she consent at the time? Like, fully 'please do the dirty with me I'm horny' consent? She was nonverbal but could she have communicated in any other way? Or did she feel she had to go along with it because she's in his care and Lydia's mythril buddies said this will help? BECAUSE THAT'S RAPE. The idea that raping someone will help fantasy ptsd (not cause it as is the case in reality) is just so unbelievably fucked up. Yes you can write it off as boinking helps chase away that evil god, but the line between 'events caused by gods' and 'natural events/conditions attributed to gods' isn't clear enough to get away with that imo.
And when she turns out to want to be intimate after all, he breaks up with her. Because the sleeping with her was just 'therapy.'
I really like the mythology and setting. I'm okay with the adventurer's guild acting like a pseudo-mafia when someone tries to fuck with it. I like how dark this series is. And it's the first one I've read that describes how a shield-user fights instead of having them in the background shield bashing (Bofuri doesn't count).
Dubious on the (misuse) of alcohol as a coping mechanism too.
Teetering on the should I drop list but uuuuurgh.
