“Mmm…”

Lily Liu had no choice but to comply. Her mind was nearly blank, her will utterly surrendered—whatever Lulu Lu said, she obeyed without question.

After a long while, Lulu Lu finally pulled away, satisfied.

“Lily…”

“You’ve been such a good girl. I’m so happy.”

She took out her handkerchief and gently wiped the tear-streaked smudges from Lily’s cheeks.

“Remember,” she murmured, “keep being obedient. Don’t even *think* about running away.”

“I’ll obey… I will… I promise…”

Lily had become a broken record. Humiliation no longer mattered.

As long as the torment stopped, she’d do anything. Obedience meant safety. Disobedience meant pain.

Lulu was applying psychological conditioning—negative reinforcement and positive punishment—to carve “Obey” and “Don’t run” deep into Lily’s psyche, until they became instinct, an unbreakable law etched into bone.

Like a puppy shocked repeatedly in an electrified cage: even with the door open, it cowers within an invisible circle, trapped by self-imposed fear.

Mental shackles, once forged, are infinitely stronger than physical ones—nearly impossible to break alone.

Behavior shapes based on consequence. Reward strengthens it; punishment weakens it.

Positive reinforcement encourages repetition. Negative reinforcement removes discomfort to reinforce action.

Lulu used both. After Lily’s escape attempt was punished harshly, she’d now *think twice*—maybe not even dare to imagine fleeing again.

Positive punishment? Adding an aversive stimulus—like the spanking Lulu delivered.

Wrong action → pain → lesson learned. Simple. Clear. (Though, of course, masochists are the exception.)

One session wouldn’t make Lily a perfectly obedient plaything. Lulu knew that.

But no matter.

Once they settled into the new place, she’d have all the time she needed.

Time was the yandere’s sharpest weapon.

…

Lulu cleaned Lily’s lower body, changed her into fresh panties, locked her back in the room. She fetched a band-aid for Lily’s finger cut, gently checked the split lip, dabbed it with saline.

She *did* care—fever or tetanus from these wounds would haunt her forever.

Then she left to pack.

Thanks to last time’s rehearsal, she moved with ease. Only two extras needed: a suitcase large enough for Lily, and sleeping pills to keep her quiet en route.

She bought them in person—supermarket for the case, pharmacy for the pills.

Walking home, calm finally settling in, Lulu reflected.

Yeah… Lily *was* pitiful.

She’d vented leftover frustration purely on yandere instinct—gone too far. No matter how strong Lily was, she was surely shattered now, seeing Lulu as a monster.

But regret? None.

This was necessary. Excessive? Maybe. Effective? That’s all that mattered.

To a yandere, even the cruelest act is love—a glorious deed.

Punishing disobedience lifted Lulu’s mood. She hummed while walking.

Worth the time.

If you’re gonna be a yandere, don’t hold back. Don’t shrink. Do what you want.

Half a day was plenty.

…

By evening, Lulu returned with an oversized suitcase and a box of sleeping pills.

The storm inside her had passed. She seemed calm again, her smile gentle—the familiar yandere mask restored.

But Lily no longer trusted it.

Her eyes wide like a startled sparrow, trembling with raw fear.

The conditioning was already taking root.

Lulu smiled faintly.

“Lily… it’s time to go~”

“…” Lily stayed silent, nodding timidly.

She knew the plan. Knew it was reckless. But resistance felt impossible.

Refusal meant punishment. Again.

She watched Lulu pack, silently praying she’d change her mind.

*If we stay… someone might find me. But out there? In that lawless place? No one will come.*

Her prayer went unheard.

Lulu finished packing.

Then she took a few pills from the box in her pocket—and offered a gentle, smiling gaze.
