Finding My Half

"How many siblings do you have?"

That would be the worst question you could ever ask Katie. She's been avoiding that question ever since that tragedy in elementary school. But no matter how far she runs away from it, it keeps chasing her. And it drives her nuts every single time. It's also the reason of her broken friendships. It brings her trouble and despair.

Katie is her name. Just an ordinary girl, or that's what others thought. She have 2 siblings. A brother and a half sister. Unfortunately, her sister doesn't know her existence.

Her father got terribly ill and is in the peak of dying. His last wish was to see her half sister. Will she be able to fullfil her father's wish? Or come home empty handed?
