They're bro in papers but not really in blood, mc has other father, his mom killed Ml's mom so his will be killed the same way. King (ml's father) hated mc and most especially, his mom so he killed mc's mom the same way she killed his first wife (ml's mom) he also has motive to kill mc but ml told him not to kill mc, by this time mc is already part of ml's life

Nu spoiler said that mc will go back to his mainland and become king (mc's mom is related to royal family) this time, ml's already in love with mc and later after having power, he ask mc for his hand in marriage

Mc and og female character is buddy buddy, I think she became a secretary or something...
