The Caged Bride and Her Ice Prince

"There are as many women as there are stars in the sky, but you're the only one I'll ever physically be with, the only one I love." Rita first met Emidio, the prince of the Empire of Grado, when she was 10 years old. She, the princess of a small country, was sent to the empire along with her dowry. Emidio had black hair and red eyes and was too handsome for the young Rita to feel comfortable approaching, but he called her his little bird and taught her what a kiss was. Eventually, the night to consummate their marriage arrived. Source: MangaPlaza
