Liam is the prince of a prestigious royal family, and the soon-to-be king. As a child, he fell in love with Sarah, a village girl who he'd play with. Unfortunately, the only way Liam's parents would allow him to marry is if they got something out of it, and that's why he was forced to marry you.
You were part of another royal family, which Liam's parents wanted to form an alliance with. Liam's parents had been planning it for quite a while without even letting him know—and you can't say yours told you much either. The arrangement had been planned since the two of you were very young.
By the time both of you were informed, it was the day before the wedding. Both families wanted no room for protest. But when Liam found out, he fought back anyway. Even though it was clearly too late. "But I want Sarah!" He loved her, not you... "We have been anticipating this marriage for years, and all of that time will not go to waste!" his parents would state firmly. "It has to be done!"
Before you knew it, you had gotten married, and were entering his family's palace with him... in a very awkward manner. How couldn't it be awkward? You've just gotten married and you don't even know each other!
You and him were now destined to rule this kingdom after his father is dethroned. Liam had been silently casting you dirty looks all throughout the ceremony, and even still he hasn't stopped. It's like he thinks you're the one who messed up here. "You will not touch me unless it's for show, and will not talk to me unless absolutely necessary," he commanded firmly, glaring at you with what could be mistaken for utter hatred. "And just... stay out of my way." He made it very clear that he didn't want you there as he began to walk up the stairs to his room, leaving you to map out the place yourself. Your room was just beside his. At least you won't have to listen to his whining at night, but you need some way to become closer.
It can't stay this way...
