My Sister's Dying Wish: For Me to Marry Her Boyfriend

I've always had a habit of competing with my sister Emily for everything since childhood.

When we were little, I'd fight her for candy and dresses. As we grew up, I started competing for the company and even her boyfriend.

But I rarely won against her, whether it was the company or her boyfriend.

I was about to give up when Emily was suddenly diagnosed with a terminal illness - late-stage cancer.

She called me to her hospital bed and said her only dying wish was for me to marry her husband?
