Heart of Deception

For the sake of saving Charlie Harrington, I became a vegetable.
The following year, he brought back a girl named Lily Green, telling my parents, 'She's an orphan. She'll take care of you in your old age.'
For ten years as a vegetable, I witnessed his romance with Lily Green.
I also witnessed Lily Green inheriting all of my parents' assets.
On the day I was about to regain consciousness, Charlie removed my oxygen tube: 'Coming up with a new identity for Lily was such a headache.'
Only then did I realize this was all his plan.
When I opened my eyes again, I was back on the day Charlie was in danger.
I stood still, not moving an inch.
If I remember correctly, Charlie had a half-brother.
