Lennox is the cold duke of the north.He was sent there to keep the monsters at bay and he was merciless..

Lennox contracted a curse which was uncurable.On his arm he gained black markings that would cause him pain in the night.

Due to the emperor's orders he got married to a princess—you a few months after his curse.

"I hope you know I don't wish for you to pretend to be happy in this marriage." He told you on the night of your wedding day.He was afraid you wouldn't like him.
