His head ached as Saeyoung finally woke up. He tried to stand up but something was holding him back. He blinked groggily in the dim light as he noticed wire strapping his wrists to the arm rests of a chair, some cable keeping his torso secure to the back of the chair and more wire keeping his ankles in place with the legs of the chair. He moved his head, seeing that he was still in the apartment and he wasn't alone.

"Sachi?"

Sachiko glanced at him from the bed. She had his laptop open before her, papers scattered around her with scribbled notes in Japanese characters and she had swapped out the cutesy pastel coloured clothes with black. A fair coloured wig hung carelessly across the pillows as Saeyoung registered that Sachiko's hair was actually black and her eyes, reflected off the light of his screen, were red. No, not quite, there was something off with her right eye, like it was half purple but half red.

"You're…"

Saeyoung wet his lips as he felt that his throat was dry. Sachiko stood and walked over to the computer on the desk which faced him. She leaned over, typing on the keyboard. The screen lit up and the bubble tea lover was there, sipping on another cup with a surprised look. She pulled away, chewing on the tapioca and swallowing before leaning closer.

"Good job, Rena! I was getting worried…"

"Rena?"

Sachiko, or Rena, nodded and bowed to the girl before retreating to the bed and continued using his laptop.

"Hey, don't touch that!" he snapped and he was ignored "What is this?! You really sent a dangerous person to the RFA?!"

"You're alive, aren't you?" the girl drawled before taking another sip.

"What is this? Who is she?!"

"Aw, spoilers much?"

Saeyoung glared at the girl as he tried to free himself but the wire was cutting into his skin. He glanced at Rena who was still looking at his screen and scribbling on a new piece of paper. She was working like a robot, she could give Jaehee a run for her money.

"How did you even get access to my computer?" Saeyoung demanded "How are you able to hack into it?!"

"Hey, you and Saeran are like twenty-two and can engage in hacker wars," the girl drawled.

Saeyoung glanced at her then glanced back at Rena.

"You're an agent?"

Rena didn't respond as she reviewed her notes.

"I guess you could call her that," the girl answered for her.

"Why is she…? Are you working for Mint Eye?"

Rena barely blinked as she set a few pages together then turned to grab a fresh piece to write on.

"Rena's wonderful, I'm proud of her," the girl smiled "Have you seen her drawings? When she was around nine she would take a week to draw one but she's improved so much."

"What is she looking for?" Saeyoung demanded "Please don't tell me you created a new agency that's just going to complicate the timeline?"

"Nah," the girl shook her head "I would classify her as a freelancer in this world."

She leaned in.

"She's quite a linguist despite the lack of her tongue, you know?" she smiled "Korean, Japanese, French, English, Mandarin and Cantonese…the list goes on. She knows sign language and Morse Code too."

Saeyoung glanced at Rena then glanced at her feet which were in high heels.

"Even Arabic so she'll be able to get into your place if need be."

"You actually have to speak to be able to get in," Saeyoung raised an eyebrow.

"I can use a software on my phone to dictate for me."

Saeyoung glanced at Rena sharply as she held her phone with one hand and wrote with the other. She then typed something else into the phone to repeat it in Arabic.

"How can you possibly know that amount of martial arts and languages and hacking? You're twenty-one!"

"Didn't you recognise my birthday, Saeyoung?"

Saeyoung glanced at the girl who folded her arms, crossing one leg over the other, the rattling of chains echoing in the small room.

"First of January in nineteen ninety-six was when I was born or did you forget? Rena's birthday is the tenth of April nineteen eighty-six, she's in her thirties. And she had martial arts training since she was twelve and officially became a freelancer when she was fifteen. She's had plenty of time to learn these skills."

Rena suddenly stood up and stalked over to the dresser. Saeyoung watched as she picked a mask up and put it on. It covered her face save from the left corner.

"Oh, are you off now, Rena?"

Rena approached the computer and nodded.

"Don't let us keep you now, drive safe!"

"Hey!" Saeyoung exclaimed as Rena snatched up his car keys and left the apartment "Wait, where is she going?! What was she doing with my laptop?!"

"Oh, Saeyoung, I thought you'd have it figured it out by now."

Saeyoung glanced at the girl as she adjusted her top and stretched her arms.

"She only works for two people. Herself and I."

Saeyoung stared at the computer with growing dread as the girl leaned forward and smirked.

"Didn't I say that she'd be the answer to the stalemate?"

Saeyoung thrashed in his bonds.

"No, wait, she can't!"

"Apparently, she can."

"Why do you want to go back so desperately?"

"Saeyoung, I don't belong, I'm not supposed to exist in this world and I've spent enough time here. Just by coming into this world, I did a lot of damage and the least I can do is fix what I can."

"Everything's just fine!"

"Everything is not fine, Saeyoung. Look at you! This is not your character and you know it! If you just let me do the hard reset then I can fix everything!"

Saeyoung looked afraid and the girl's eyes softened with sympathy.

"Yes, it's scary to have memories wiped like that but it'll be the best solution for everyone. I don't know how long it will take for Rena to get here but just sit tight and let it happen."

The screen went black and Saeyoung's eyes darted around, locating his phone. He needed to be quick.
