I somehow dont like the priest. He just Judged too fast, like he knows everything.

He's just a naive dumbass. He never once considered a romantic situation because he knows nothing of romance. Overall, it only makes him slightly annoying.

I don’t even care about that. I would have let her find on her own why she felt like this and giving tiny hints where she could search for the answers. But he said: it’s like this.

That's where the Naive part comes in he genuinely thinks he is helping because he has limited knowledge on how most people work.
