Linhardt von Hevrig - Fire Emblem: Three Houses
I really liked all of the Black Eagles from 3H, but Linhardt really really endeared me. It's very funny that excluding the DLC, he is one of the only gay romance options, lol. His squeamishness at the fighting and blood is very endearing and silly to me as well, it makes him really feel like a scared teenager fighting in a war he didn't ask to be in.
I also like that Linhardt offers a very casual representation of depression. I don't think it was an intentional reading of his character necessarily, but his constant exhaustion and lack of interest in things felt very quiet and powerful to me, especially considering the quiet way his friends still engage with him. It reminded me of my friends knowing something was wrong with me, and instead of making a big deal about it, they would just let me sleep on their shoulders whenever I would say I was tired.
