Ending needed to be more gonzo frankly. I want the time loop to spiral out of control leading to an orgy between the two main characters at like every year of their lives, all together. Fucking each other, fucking themselves, then fucking each other, then fucking the very fabric of time itself.
Instead we got this which is dumb but boring and doesn't lend itself to thought or creative interpretation because we're supposed to take it at face value but also conveniently ignore that the POV character just committed like 24 chapters worth of statutory rape.
Meh
