Cheated of My Child, I Rewrite Fate

My son, Ryan Fischer, gets into a car accident and urgently requires a blood transfusion. I get on my knees and beg my widowed sister-in-law, Serena Lowe, to donate her blood to him. However, my husband, Neil Fischer, stops me.

"You can't use Serena's blood, because she's Ryan's actual biological mother," he says.

I fail to understand the meaning behind his words.

"Although Serena helps me take care of Ryan, he's still my child in the end!" I argue.

After a momentary silence, Serena kneels before me.
