Chapter 126: The Moment Tina’s Heartbeat Began

“T-That, Tina…”

Su Xiao Zi’s sudden suggestion made even Tina stutter.

Tina couldn’t calculate human emotions with data, so she didn’t know the optimal response.

But she was far more obedient than Su Xiaoxiao.
Both Su Xiao Zi’s and Su Xiaoxiao’s words were absolute commands to her.
In combat missions, they were her direct superiors.

Tina only followed orders from direct superiors.
Even higher-ups outside the chain would be refused.

So in the end, Tina passively let herself be dressed in the maid outfit.
She showed no resistance—calm as if simply changing clothes, just like her usual outfits that Su Xiao Zi always prepared.

Su Xiaoxiao, watching from the side, began to envy Tina.
Her complete lack of shame was incredible.
She handled anything with total composure.

Su Xiao Zi personally held Tina’s small foot and slipped on the shoes.
They matched Su Xiaoxiao’s exactly, except Tina’s stockings were black-and-white striped.

The antennae on her head were removed and replaced with cat ears.

“Tina~! Tina! Tina! I’m your biggest fan!!
Quick, let’s take a photo!”

Su Xiao Zi waved a glow stick like a hardcore fan, all restraint gone, cheeks flushed with excitement.

Su Xiaoxiao lay on the bed, smiling at the scene.
Her little sister had always been like this—explosively excited about things she loved.
Back when she had no little sister to spoil, now she suddenly had so many, and she could dress them up like dolls.
No wonder she was this thrilled.

Tina, hearing “photo,” simply turned sideways and held up a peace sign.
Her expression remained blank—zero emotion visible.

But even that satisfied Su Xiao Zi completely.
At the beginning, Tina avoided contact outside of missions, spending all her time in sleep mode at base.

She used to feel cold and distant—an ice queen with no expression.
Talking to her was like stepping into a freezer.

Seeing her gradually become more active was already a huge improvement.

Su Xiao Zi searched for the perfect angle, twisting her waist gracefully, the short skirt swaying.
Evran stood with arms crossed, carefully observing the two little maids, who knows what strange thoughts were brewing in her head.

(I need to find a way to sleep with both of them.)

“Alright, now both of you sit on the bed, facing each other, and get really close.”

“Huh…? Why do we have to do that?”

Su Xiaoxiao hesitated.
Tina didn’t mind and simply followed the instruction.

“Then—hold each other’s hands, fingers interlocked~”

When Su Xiaoxiao took Tina’s hand, something in her chest tightened.
Tina’s hand was soft, cool, and white.
Interlacing fingers like this felt strangely embarrassing.

“Hm?”
Tina noticed Su Xiaoxiao’s quickened heartbeat and asked blankly,

“Instructor, your heart rate is elevated.”

“I know, I know! Don’t say it out loud!”

Tina’s innocent seductiveness made Su Xiaoxiao even more flustered.
She took deep breaths to calm her racing heart.

“Now, Evran, use the red string to tie their hands together—gently, no force~”

On the bed, two little lolis in black-and-white maid outfits, both wearing cat ears, sat facing each other in duck pose.
One hand interlocked with the other, tied with red string, and both turned their faces toward the camera.

*Click.*

The camera captured the breathtaking scene.
Su Xiao Zi was so satisfied she nearly rolled on the floor.

Su Xiaoxiao stared at her with a dumbstruck expression.
Where did she learn these embarrassing poses?

At least it was over.
Su Xiao Zi seemed to have gotten her dream photo.
She hugged the camera, scrolling through the shots while Evran leaned in to look, both giggling.

Su Xiaoxiao finally let out a breath of relief.
The humiliating ordeal had reached its end.
Good job, me. Good job, little Tina.

But their hands were still bound.
Su Xiaoxiao reached out with her free hand to untie the red string—
only for Tina to press it down.

“Hm? Little Tina, Big Sis Xiao Zi’s embarrassing game is over now.
You don’t have to keep cooperating.
Let me untie it so you can go eat ice cream.”

Tina didn’t answer.
She just stared intently at Su Xiaoxiao.
Something felt… off.

Su Xiaoxiao wasn’t sure if it was her imagination, but when their eyes met, Tina’s usually vacant pupils seemed to shimmer with faint emotion—and tremble slightly.

“W-What’s wrong?
If you want something besides ice cream, you can ask Xiao Zi for a reward.
You cooperated so well with her embarrassing game.”

Su Xiaoxiao tried again to free her hand, but Tina pressed it down once more.

“Don’t untie…”

In that instant, the words from Tina’s mouth froze Su Xiaoxiao in place.

She stared in shock, slowly lifting her head.
Tina’s face, always expressionless, now held a faint, fragile light.

For some reason, Su Xiaoxiao heard sorrow in those words.
She blinked, stunned.

“Don’t untie… Don’t… separate again…”

“I’ll protect you…”

In that moment, a vision flashed before Su Xiaoxiao’s eyes.

It was *her*—

Back when Su Xiaoxiao was still just an Exterminator trainee, her instructor…

The same face, the same voice.
But after that day, they were no longer the same person, no longer the same memory.

Code name: Tina.

Two years ago, her last words had been—

“I’ll protect you.”
