This is SO MUCH FUN! Arisa is just so naively cheerfully squishable, just derederederedere, and Mari is such a quiet shy sweety pie. Happiest amnesia story you could ask for.
Hahahaha!!! I'd been wondering how they could handle the "source of the amnesia" thing, because I just couldn't see something tragic going on that she'd have to block out. Perfect!
She said her last memory was proposal at the park so my guess would be that she doesn't remember anything that happened during the time she had amnesia.
