I'm new to reading novels and have read a very small amount of actual novels/books but i read manga for a long time and one of the themes I love is the profound impact of trauma and resilience, and the struggle to find hope exactly like in Berserk, with how Guts's trauma affects his mind. Another example, is, more recently, I have been reading Shadow Slave (Webnovel) and am well past halfway done with it, and I the way the author, sometimes subtly or explicitly, describes what's going on in Sunny's mind, with his trust issues, paranoia, and other things. Any other novels, webnovels (preferably fantasy) that have any similar thing like that? Also possibly have a small complicated romance subgenre, kind of like how the relationships between Casca and Guts and Sunny and Nephis are complicated and strained.
