"I’m so lonely. All the other humans are scared of me, no one talks to me. No one wants to be my friend, they think I am too powerful. They sent me from nations to nations in their name and to defeat a world ending threat, they fear me more and more. I am a victim of my own success, 'generic isekai protag #31049531'. I don’t even get a real name or personality, only a bland descriptor. I am capable of so much more and no one sees it. Some days I feel so alone I could cry, but I don’t. I never do because what would be the point? Not a single person in the entire world would care."
Sorry I just had to in regards of the princess stating he was lonely.
