This year the crazy folks at [\#email@example.com](irc://irc.rizon.net/lamonae) decided to offer you a release for Valentine's day. This episode is indeed very romantic.
Today's heroine, Yurika, has returned to Japan from a long period abroad, and is trying to get back to normal life in her real home. She has great piano skills (maybe some "Piano Touch" as well :o) and great family, and even a boyfriend. But she has also serious health problems, and this may affect her as much mentally as physically. Will she manage to overcome her sadness, in the arms of her boyfriend? This is the issue developed in this episode.
On an historical note, this episode and the follow-up (ep 24) were meant to launch a sub-series with a new romantic heroine, replacing the Ami series in the heart (and pocket money) of customers. This did not really work as the whole story is probably a bit on the boring side. Therefore the producers made later on more Ami episodes instead of developing the Yurika story (with Ami Sorekara, to be subbed, trust us lol).
