In the same situation i wouldn't trust the princess, especially since she was the summoner and tied to the nobility who were trying to kill you from the beginning.
She might have playing airhead or something, no one knows
@mrmm It would be hard to betray your soul even with a lot of brain washing from your little sister even though you are trained by the kingdom and the church to be loyal to the hero, support and love him too.
He don't want to be bothered by associating with the First Princess, but punching the Second Princess in the face inside of her own castle isn't a bother at all. I mean, punching a princess in the face in public obviously comes with no repercussions at all. MC logic is astounding.
@degenerateafro He wants to punch her though. He is willing to deal with the bullshit afterwards in that case so its fine. This is troublesome and has no reason making it seem less so.
