Credits for the BOYS' LOVE PC & PS2 Visual Novel / RPG "Teikoku Sensenki", roughly "Chronicles of the Thousand Wars Empire". No translation exists. Takes place during the period of rebellion in China against Emperor Yangdi of the Sui Dynasty. Developed by Langmaor. There's also a pure Yaoi add-on disc for the PC version of the game. The add-on also has some S&M elements in it.
I think the music and the pictures are worth checking out.
