Chapter 2His Obsession Beyond The Sibling Bond

I had truly been raised by my brother.

I heard that in the beginning, he hadn't wanted me. Even as a small child, he had his own sharp logic. He’d argued against my mother's irresponsible behavior:

“She’s your baby, Mom. She’s not my baby.”

My mother had been amused. “Why isn’t she yours?”

“Everything in the house will belong to you someday, and that includes your little sister.”

Declan took the line to heart.

From then on, he became my willing, tireless Nanny-Brother, taking charge of everything. When I was sick in the hospital, my mother would stammer in response to the doctor's questions; Declan would answer fluently and perfectly.

Even my mother had once marveled, “Declan, you really have the instincts of a parent.”

Declan took it as the highest compliment and doubled down on his care.

Even now, he was standing in the doorway, his expression a mix of weary tolerance and total certainty, as if I was the one being unreasonable.

I wouldn’t meet his eyes. “Dec, I’m an adult. I can take care of myself.”

His voice was flat. “You said that last time, and you ended up in the ER with a migraine.”

“That was just an accident—”

“I can’t afford another accident.”

“But this… this is wrong.”

Seeing my hesitation, he pushed the door open, easily slipping inside the room.

He tilted his head, his expression a picture of genuine confusion.

“What’s wrong about it? You’re mine, Baby.”
