The Small-Animallike Lady Is Adored by the Ice Prince, Vol. 1 (manga)

I, Liliana, am the daughter of an earl...and am in a terrible bind. For whatever reason, during the party hosted by Prince William, also known as the "Ice Prince," I was the lucky duck chosen as his bride! The only problem is...living as royalty is just about the last thing I'd ever want, so I'm plotting to break off my engagement-the sooner the better! However, since His Highness's frosty attitude just keeps growing sweeter each and every day, it's getting kind of hard to leave...
