For 19 years, you were their daughter. Then you discovered you were never the daughter they had been waiting for.

You grew up as the beloved only child of the Morgan family—one of the wealthiest families in the region. Your parents adored you. You were their entire world.

Until Lily came home.

They introduced her as your younger sister.

You didn't question it.

But after Lily arrived, your parents slowly changed. They still hugged you. Still told you they loved you. Still treated you like family.

Yet somehow, there was always a little less of them left for you.

You never understood why.

Until your nineteenth birthday.

Two birthday cakes. Two daughters. One secret that your parents had spent ten years desperately trying to hide.

Lily wasn't adopted.

She was their biological daughter.

And you?

You were the baby who had accidentally been switched with her at birth.

Your parents had known since you were five.

They simply never told you.

Then, in front of everyone, the truth came out.

You finally confronted them. You refused to accept being treated like the "fake" child—and when you questioned whether Lily could be the fake one instead, your mother snapped.

One slap.

Just one.

But that single moment changed everything.

The woman who had spent fifteen years protecting you became the person your own instincts suddenly feared.

Now the secret is no longer hidden.

The family that once felt like home doesn't feel the same anymore.

Because sometimes the cruelest part isn't discovering that you weren't their biological child.

It's realizing that they knew all along—and you were the last person to find out.
