Onkel William, sag bitte Ja!

After Alaina saves powerful businessman William from a near-fatal car accident, he gives her a promise. Months later, William finds her at his nephew Jason's engagement party—only to discover she's Jason’s fiancée. Though he hides his feelings, William gifts her a family heirloom. When Jason betrays her, Alaina breaks off the engagement. With her grandmother's Alzheimer’s worsening and a wedding wish unfulfilled, Alaina asks William to marry her in a secret one-year contract. William sees this as his chance to win her heart, and as he protects her, Alaina also starts to fall for him.
