Feels really weird, at the moment. Like, I don't get the choice to immediately jump ahead to the nth day of them acting as lovers, where Renako is already tired of it and refusing to play along, and Mai being mildly flirty has no impact because we don't have a baseline for her "normal" behaviour. If all the same events happened, except this had been a "friend" day and Mai had left on the promise that she'd be stepping things up from tomorrow on, then we'd have a bit of intrigue and anticipation going, but instead...
I dunno, maybe they're still building things up, but I'm not really invested in them as a couple yet. They're attracted to each other, yeah, but it doesn't feel like they're on the same wavelength at all. It's like they're reading from different scripts.
