Yeah, he hasn't done much protecting of anybody so far. And he's plainly told her he can't go against the princess, so there's only so much he can do. He's useless.

And yeah, 99/100 of these "reincarnated for revenge" stories would end really early if the MC would change cities and hang out with a new crowd. But I've seen at least one where the MC deliberately avoids making changes in order not to mess with his reincarnator advantage, and at least two more where the MC sticks with the same career because she doesn't want to do anything else except that.
