Does anyone else have an issue where they can't relate to the MC at all? like I'm a guy and I would get married to the FML in a heart beat. Like ok I know his family is dead and he's messed up mentally and he's also kind of a prick but you're telling me any average joe would really just reject this girl?
He's very much not a prick. He shows an awful lot of concern for her wellbeing and future. We've known the guy for two chapters, and the story so far was that back when he was a kid here, he had an experience that people described as supernatural. But he has no idea what it was. All he felt was afraid, and like it was covered up. He came back to solve the mystery, he's got all sorts of books on folklore that he's marked up.
When he goes back to the mountain, he can't help but feel like he's seen all sorts of things before. He's been places. He's done things. He remembers doing them, but he doesn't know how he does. He has an experience where he walks off the path and meets a giant wolf, but it seems like it doesn't actually
happen and instead he stayed where he was the whole time. He's wrapped up in trying to solve this mystery, figure out what happened to him, figure out what's going on... and then he meets her again and she's like "we're married now"
Throwing his entire life away to live in a magical castle sounds pretty cool. I can get the idea that it'd be hard to resist. But he didn't come back aimlessly or when he was at the end of his rope. He was trying to solve a mystery, and suddenly he's supposed to live his whole life not only
there, but totally outside of human society. He doesn't know her, and he thinks she doesn't know him. The conversation they have where she decides to live in the outside world explains his philosophical motivations pretty clearly: he doesn't think its fair for people to be forced to live in a way they don't want to. He couldn't let this lady he essentially just met
today after coming back to solve a personal mystery get tied down with him for her whole life. He tells her she can marry whoever she wants, or not even marry at all, trying to convince her that she has no reason to decide to stick with him just because of rules.
See, it's not just him who'd give up the rest of his life. She would, too. His motivation is clear: he doesn't want to be her anchor.
