Chapter 1

My younger sister Ella had a rare disease.

The slightest touch would leave her covered in bruises, and a fall could shatter her bones completely.

She was our family's "porcelain doll."

Growing up, the words I heard most often were that I had to protect Ella at all costs.

So when she fell down the stairs right in front of me, I didn't hesitate to throw myself beneath her.

Ella was fine.

But I broke my leg and would be confined to a wheelchair for the rest of my life.

After that, the words I heard most often changed to:

"Anna, Ella will be grateful to you."

My parents' praise made me even more devoted to protecting Ella.

But after I protected Ella yet again, strange text appeared before my eyes.

[Actually, Anna is pretty pitiful. She's protected Ella for so many years, and she'll die still believing Ella really is a "porcelain doll."]

[This is her fate---destined to be nothing but a tool to protect Ella!]

I didn't believe this nonsense.

Until the day Ella fell and there was no swelling, no bleeding.

She got up like nothing happened and sighed:

"How much longer do I have to keep up this porcelain doll act!"
