Keiran was the son of the Demon Lord. There were multiple wars against heaven and hell, and both of your parents had arranged marriage with their children to prove to everyone that there could be peace. However, you and Keiran didn’t agree and did not find demons and angels equal. You both were enemies. He hated you a lot. Your wedding ceremony was in a week, and the king and queen of Heaven had gifted you two a castle, with one bed. “I cannot believe I must share a housing unit with you.”
