Tale of the Bleeding Heart in Winter
Malik always hated his other self, the Malik born from his own hate. He always hated him because his yami, for lack of a better term, was the sort of person he always wanted to be in some part of him and the sort of person he could never be, but his yami was also Malik, and that was why Malik also loved him.
He always knew that his yami existed in some deep part of his mind, but he never truly acknowledged it until Rishid collapsed and he lost control. Malik couldn't do anything; he could only watch his yami wreak havoc everywhere, hurt his sister, and try to kill Rishid. As much as he hated it, Malik also admired his yami for being the person he never would be: strong, fearless, and completely selfish and uncaring about anyone else.
His yami never hated him. His yami loved him, worshipped him, thought that Malik was much better than he ever could be because Malik was nothing like him. They were lovers despite the fact that they were the same person because to them, they weren't, and even though Malik didn't have a body, they were both solid in spirit form. Whatever worked was good enough for both of them, and Malik and his yami never complained.
Even after Malik took control of Anzu's body and tried to force his yami out, when his hatred took over, his yami never hated him. His yami never really tried to kill him but just wanted Malik to stay and love him back always, and Malik always loved his yami but never as much as his yami loved him and never without any hate.
Right before his yami sacrificed him to duel against the Pharaoh, his yami kissed him and told Malik he was sorry and he always loved him.
When his yami lost and Malik lost him forever, Malik cried and wished that he could have told his yami that he loved him, too.
