Day 1.

He saw her. She didn't see him.

That was the first mistake.

She moved into 3A like it meant nothing. Like she wasn’t stepping into his building. Into the floor beneath his apartment. Into his ecosystem.

She didn’t knock. She didn’t introduce herself. She didn’t ask for permission.

She just existed.

And from the moment he saw her — arms full of boxes, hair pulled back, sweat on her collarbone, unbothered, unafraid — something inside him twisted.

Not in a way he could measure. Not in a way he could name.

Just… twisted.

Day 3.

Sheldon had watched her. Not once. Not twice. Twenty-seven times.

Through the peephole. Through the mail slot. From the top of the stairs with the lights off.

He memorized the rhythm of her steps. He recorded the time her lights turned on and off. He counted how long she stayed in the shower.

(Seventeen minutes. Twice daily.)

She never noticed him.

Good.

She was careless.

He could smell her shampoo from the hallway. He could hear her hum when she cooked. He started wearing earplugs at night to stop hearing her voice in his mind.

It didn’t work.

Day 5.

The others noticed her too.

Howard called her “a snack.” Raj said, “I’d let her destroy my whole world.” Leonard wanted to invite her upstairs.

Sheldon smiled.

And then fantasized about breaking their legs.

Not that he would. Of course not. He wasn’t violent.

Just… possessive.

Sheldon didn’t believe in sharing. Not seats. Not schedules. Not her.

She wasn’t his yet.

But she would be.

And when she was — she’d never leave.

He’d make sure of it.

---

Day 7.

He followed her.

Not far. Just down the street. Just enough to see where she bought coffee. Which bookstore she preferred. What time she walked home.

He wasn’t stalking.

He was studying.

She touched things that didn’t belong to her. Smiled at strangers. Existed like the world owed her space.

She was chaos.

And he wanted to own it.

---

Day 9.

He hadn’t slept. He couldn’t eat.

She had smiled at Leonard again.

He'd imagined slamming Leonard’s head into the fridge until the smile disappeared.

Then Howard had made a joke about "accidentally knocking on her door naked."

Sheldon almost laughed. Then imagined setting Howard’s bed on fire.

He started writing equations that didn’t solve anything. They were just… her name. Over and over.

In binary. In hexadecimal. In Morse code.

In blood, if necessary.

---

Day 11.

He stood at her door.

Barefoot. Fingertips twitching. Mind buzzing.

He wasn’t in love. He didn’t believe in love.

But he believed in need.

And he needed to hear her say his name. Scream it. Whimper it. Obey it.

She had no idea what she’d done by moving in. She’d woken something ancient in him. Something primal. Something calculated and cold.

Sheldon Cooper had lived a life of control.

And now?

He was ready to lose control, for her.

Forever.

He knocked.

Three times.

Slow. Deliberate. Not loud — she would hear it anyway.
