Tsuma to Iu Na no Keiyaku

What a hypocrite! Francesca was outraged by her brother-in-law who brazenly dared to show up at her husband's funeral. He never came to see her husband after he fell seriously ill, and she'll never forgive him for that. However, her husband's will completely blindsided her—unbelievably her husband asked his brother, Guy, to marry Francesca and take care of her for the rest of her life!
