Becoming the real heiress with cancer

I was linked to a Sickness Transmigration System.

It dumped me into the body of the true heiress, despised by everyone.

Everyone adored the fake heiress, who'd been carefully cherished by the family for sixteen years.

My three brothers feared I'd try to claim what belonged to the fake heiress, so they constantly mocked and taunted me.

My biological parents were terrified my presence would upset the fake heiress, so they went all out to make it up to her.

They never once considered my feelings.

They saw my desperate yearning for love as a threat, as sheer jealousy.

Later, I was dying.

Even later, my second brother found the diary hidden under my pillow.

They fell apart.
