Please find the title

It is historical Korean BL. European countries. ML is a king who was feared and respected. He killed all his brothers and anyone that could be threaten his throne, except for one brother who seems meek. He was killed by the same brother he spared. MC then reborn into an ordinary family of workers (or slaves, I forget). He born with the almost similar face from the king he used to be. When ML saw his face, he took him to the palace. Hating his situation, he try to touch magic source as he's a talented mage when he was a king. There some magic that bound with his soul that he can use, but unfortunately it is shackled. ML finds out MC's intention and try hard to make him away from any magic source. By some events, MC able to run away from ML with ML's white haired trusted subordinate. At this time, there's no certainty, but ML and that white haired seems to know MC's true identity. Then I couldn't continue because the chapter stop at that. I wish to find this manhwa once more.
