And now let's switch things around to the opposite: an old-school series set in (what were then) modern times.
A series that's literally as old as I am.
...oh dear.
CIPHER, by Minako Narita. First published in 1984 and first published in North America in 2005.
PLOT:
One day, Anise manages to gather up her courage to confess to her handsome famous classmate Siva. What she wants is not a romance but his friendship. Amazingly, he accepts her offer but remains cryptic and cynical. Eventually Anise discovers his secret: he and his identical twin brother Cipher have been switching places on a regular basis. Anise is furious at the deception and presumes the two do this just to hold everyone at a distance. She's ready to disclose their secret, but the boys counter with a bet: if she can tell them apart after two weeks, they'll tell her everything. If she can't, she has to keep their secret forever. Anise is determined to win, even if it means moving in with them.
