Why should humanity rely on any gods? [Half huffy, half curious. Humans have gotten along without any evident interference from gods. The only thing possibly lauded towards gods were luck/probability and occasional "wtf nature" moments that inevitably get explained by science later on. Though no one's been able to tell where or why Quirks happened... but hell if Katsuki's gonna attribute that to gods. Save to say he and Yato are from different worlds and that's the explanation.]

Like living with a bunch of amnesiacs. [At least Yato gets to sit in the "new boyfriend" field rather than "unpopular boyfriend" field when it comes to Hiyori's family. Sucks he has to keep being reintroduced, further pounding into his head the crappy fact he's not a popular god each time. Katsuki obviously can't help with it, but he hopes the guy manages to get out of that rut when he returns home and kicks some fucking ass to the top.]

You're not who you were right now. [He doesn't have to be shackled to that past self, only learn from it and move forward. Katsuki knows well enough about self-disgust and shame over the person he used to be or things he used to do. There's no running or escaping from it, nor should there be, but improving and learning from it? Yeah, that's what makes them who they are now.]

Hmph, you're gonna knock yourself out standing up that fast. [Says the guy who's shot to his feet faster than lightning a billion times in his life.] Get me a popsicle.
