"Fancy seeing you here," the interrogator started, "Miss Minatozaki."

The perpetrator smirked. "Miss Im."

Im's eyebrow twitched, "Do you know why you're here, Sana?"

"Well, Nayeon." Sana's smirk turned into a sweet smile. "I guess I'm here because I've done something wrong?"

"And what do you think is that, Miss Minatozaki?"

Sana laid her chin on her palm, having a little bit of a hard time as her arm was shackled to the table. "I don't know. How about you tell me, Nayeon-ssi?"

Nayeon snapped and stood up abruptly. She was about to lose it until she remembered that there are people watching from the other side of the mirror.

The interrogator took a deep breath and leaned on the table. "It is said here-" She brought up a folder and tossed it in front of Sana.

"-that you tried to kill the chief inspector while working in a crime scene. With me."

Sana chuckled and leaned towards Nayeon, "I think that you and the people behind the glass-" she motioned to the mirror, "-believe this because you've seen me do it, right?"

Silence surrounded the room. The blonde girl smirked and leaned back to her chair. "I figured. Since you know what happened and you've seen it with your own eyes, you don't need to interrogate me anymore. The evidence is right in front of you. You may now leave."

Sana gestured to the door with her chained hands. The inspector glared at the woman in front of her and picked up the folder then walked to the door.

"We're not done yet, you two-faced killer." Nayeon stated before completely coming out of the room.

The perpetrator's smirk turned into a sad smile.

"I guess we're not."

The door was slammed closed. A chair was turned and sat on with a thud. The person sighed and ruffled her hair out of frustration. Nayeon opened the folder and read the contents.

"Why? Why did you do this? I trusted you," she muttered to herself.

Minatozaki Sana. Her partner. Nayeon's partner for more than one year. The woman she trusted for a long time. When they were together in their cases, Sana was always smiling, positivity radiating from her. She was optimistic when Nayeon wasn't.

Now, she's- 

Minatozaki Sana. A perpetrator. A killer.

The opposite of what Nayeon thought she was.

A knock on the door snapped Nayeon out of her thoughts.

"Come in." The door was ajar. And a head went through the small gap, revealing a beautiful girl.

"Miss Im? May I come in?" The girl asked.

"Yes you may, Tzuyu." The said girl opened the door wider and went inside the room, not forgetting to close the door. "Is there anything you would like to say, Tzuyu?"

"Ah yes. The chief inspector is asking for you. He wants to come as soon as possible."

"Oh okay. Thank you. You should've just called me so you didn't have to go here." Nayeon cleaned up her table, taking the folder with her.

"I know. But I want to make sure you're okay." At that, the older one smiled genuinely at her secretary.

"I'm not okay now. But I will be. I just need to have some time to cope with it." Nayeon knew that she can't lie to Tzuyu. The girl would just read right through her.

"That's good. That's all I need to know. I'm going now, Nayeon-unnie." Tzuyu bowed and went out of the room.

The inspector sighed and went out of her office with the folder in her hands.

Nayeon felt her phone vibrate, signalling that a message was sent to her. While walking, she fetched out her phone and looked at the message.

'It's going to be alright, Nayeonnie. I'm here for you anytime you want someone beside you. See you later. I love you!' - Jeongyeonnie

The older one smiled and chuckled to herself.

She sent back a message to her bestfriend and hid her phone in her pocket again.

Nearing to the chief inspector's office, Nayeon stopped in her tracks as she heard a deep voice talking.

"We're going to continue Breakthrough. The girl's being interrogated now and she's has no chance of coming back again alive. I've already told the guards to make sure her life's going to be hell."

Nayeon's eyes widened and then hid behind a wall as she covered . She then remembered whose voice it was.

It was from the Chief Inspector, himself.

After all of that she has thought of Sana being a perpetrator and a traitor to her job, the blonde girl was right all along.

Nayeon thought that if the chief will know about her knowing his plans, he would do the same thing to her.

Nayeon fixed herself and when her boss was inside his office, she went inside with a blank face.

"Sir Jackson? May I come in?" Nayeon knocked on the door.

"Yes. Yes you may, Miss Im. Please take a seat in front of the table." The employee obliged.

"So, Miss Im. How's it going with Miss Mi
