エンドレスセレナーデ

Yuji can't deny it – he's infatuated with Satsuki. She's the center of his every waking thought, the star of his every wet dream… There's just one major problem. Satsuki is his late brother's fiance. Now, a year after his brother's death, Yuji is hoping the day has finally come to make his move, but a steamy night with Miki, the shy red-headed girl at work, could change everything. Should he be with the girl he's always wanted, or the girl who's always wanted him? [From AniDB]
