To be honest, I wasn't expecting to discover another Emi Wakui（和久井映見）song that I would like but I was happily proven wrong. After all, I've always seen Wakui far more as an actress than I ever saw her as a singer.
I can't really go into the nitty-gritty of why I think so, but her "Mirai kara no Tegami" (A Letter from the Future) just sounds so early 90s J-Pop. Maybe it's the way that the arrangement of the song sounds somewhat ZARD-ish. In any case, the down-to-earth pop by Hirokazu Ogura（小倉博和）is quite appealing to me. The lyrics by Rui Serizawa（芹沢類）talk about that final goodbye between a woman and a man going on their separate paths.
The song is on Wakui's 4th original album "Dareka ga Anata ni Kissu Shiteru"（だれかがあなたにキスしてる...Someone is Kissing You）which came out in November 1992.
