dark dude fell in love with the prince when they were kids and the dark dude saw the prince playing in a field of flowers. the country the prince is from is very poor so the queen tricked her son into leaving the country under the guise of a 'study abroad trip' to learn about the world, in reality the queen sold her son's body for the night to the highest bidder which was dark dude. queen sold her son because they needed money for nii-san's coronation.
the body guard in all of this is also in love with the prince and supports him even though he knows the prince is being raped for money.
prince goes back to his home country, dark dude follows and continues to rape him so that dark dude will continue to donate money to the country. the prince is fine with it because he's in love with his nii-san. dark dude talks to the queen and finds out that the royals in this country artificially breed because every generation the 2 brothers will always fall in love with each other, it's the curse of the family or something.
anyways prince wants to find out why the dark dude hates him so much so he sends his body guard to snoop around and the dark dude tricks them to his home where he rapes the prince again and that's when the prince figures out dark dude has just been in love with the prince this whole time.
at the end they find out nii-san died in an accident so security from the country comes to retrieve the prince who is now the new king. the dark dude doesn't want to let him go because if he does he'll never see the prince again.
can someone explain to me.... i dont quite understand ヘ(。□°)ヘ
