Endless Serenade (2000)

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?
