Being loner is irrelevant, this MC is just plain ass rude AF. Dumb people would say "this royalty is so trash", well guess he just ignored the kings brother and being informal towards the princess in front of him, so yeah the mc saved him but the MC is being a douchebag, so I think a little something to get his attention wouldn't hurt. In case everyone forgot, he is still a commoner and the other is royalty, and this is not 21st century woke earth lol
