The one fucking him "the lord" is not the current seme, in the past maybe it's an authority figure and Kwon the knight fell in love with the lord, meanwhile that long sharp hair dude fell in love with kwon and witnessed their love making
But the Lord only see him as a mistress, just the to warm his bed and suddenly Lord married a woman and kwon heart broken and met the current white hair seme, they're close but kwon still can't move on from the lord, but then suddenly kwon kind of get attached to the white hair seme. And the white hair could feel it too, but then Kwon somehow got called by the Lord and the lingering feelings still there, and white hair seme got mad and kill the lord
