My opinion is that they're both annoying, petty, clueless (mostly the MC, as usual) and childish. I can understand why Jaye acts the way she does, but that doesn't take away the fact that she's irritating to deal with. That ending scene where he showed up just made me chuckle because that's definitely something a character like her would do. As for the MC... well he's a blubbering idiot, which isn't too different from most games on this site, he's surely not close to the worst tho. He's constantly making th situation worse by not attempting to talk when given the chance to. The whole ski loge thing when and after Mallory showed up was weird because he didn't even give Jaye a passing thought or remembered the call before the snow storm.
It's all frustrating as fuck and I love it! This is some good storytelling! I'm actually kinda invested in the characters and the story. Like some people I had the suspicion that Mallory was Mc's long lost sister at some point during the kiss. ofc I had the passing thought when Mallory was in her car, but the kiss is what solidified it. until the "after credits" scene came up and sent my theory outta wack.
Anyway, I don't know if the dev is here but, you got a nice thing going here!
