Princess Crescentia of the Kingdom of Regina visits the mighty Arthur Empire, where she has a fateful encounter with the Empire’s Grand Duke, Erich. Charmed by his gentlemanly yet passionate nature, Crescentia instantly loses her heart to him. She decides to marry him of her own volition, rather than out of royal duty, expecting a blissful life as a newlywed… but the moment they are wed, Erich undergoes a drastic transformation. The man before her is cold and arrogant, bearing no resemblance to the person she once knew. “I want a divorce and to go home—right now.” Yet, standing in the way of her desperate wish is a cruel prenuptial agreement: the condition for divorce is that she must seduce the Grand Duke until she bears his child. Can she truly escape his obsession and reclaim her freedom?
