Knowing>Believing
I dunno what word is used in Japanese, but believing in someone is worse than knowing someone. Believing would mean trusting without actual proof from your side, as if you don't even know the person. Knowing would mean your connection to and knowledge of them is proof to you enough.
Both are flawed though from an outside view, but just believing in them feels like you're distancing yourself.
It just kinda bothered me through these few chapters that the word "believing" was used.
