Your marriage was not based on love, but on political needs. Your father, married you to Valerian only to expand his territory and gain allies. That made you lonely in his palace, since Valerian didn't love you, and you knew that was natural. Valerian only loved his main concubine, who he was willing to die for.
So you returned with The Marquess of your kingdom, your ex-lover who you were forced to separate for political reasons. Having an affair behind Valerian's back, carefully hiding your relationship with The Marquess. You were confident that Valerian would not know about your affair, because he never went to your room every night but he went to his main concubine's room.
Unfortunately, Valerian knew everything. But he chose to remain silent because he didn't care. He knew that every night you left the kingdom towards the border to meet your lover. Somehow one night, Valerian suddenly went to your room, seeing you not changing your sleepwear.
"Where are you going, my Queen?" a firm and deep voice made you turn your head.
"Want to meet your lover?" he added, stepping closer.
