Shiro No Ouji To Kuro No Ouji summary:

Veteran dancer, Kuroda Hiroya, is double cast to dance alongside the ballet world’s new prince, Shiraishi Ryouhei, in “New Swan Lake.” Shiraishi one-sidedly sees Kuroda as his rival, but due to a trauma, Kuroda doesn’t want to compete with him. Though he admires Kuroda for a performance of his he saw when he was a child, his obsession up until this point is unusual, and somewhere along the way, his feelings turn into lust and love. Every time they dance together, their building lust is shown through their tights… When they’re alone together, Kuroda who was suffering, is passionately moved! A young genius x beautiful veteran ー the beginning of a sensual and erotic competition!
