You don't know how to answer this, but all you know is your colleagues agree with you that it's weird. People have been missing. No one has any idea why, nor do they know who is the one kidnapping these people. The case has run cold because the police can't find any evidence. 

" There's no pattern correlation. " Donghyuk says. 

You sigh. 

" Ugh. This case is driving me insane there's been nine people missing just from one week there's going to be a tenth victim soon if we don't figure out what's going on. " You groan. 

" Okay. But let's think about the first two victims. They both went missing together at the same time. Now, what are the possibilities of that happening? " Jiwon asks

" They could be classmates, friends, lovers, or family. " Donghyuk answers. 

" Any other thoughts? " Jiwon asks

" Alright so I know this sounds insane but listen to me, you said the first two victims disappeared at the same time together. We're all sure there's going to be a tenth victim. Have you all noticed when the victims go missing, they're in pairs, or the number of people reported missing by the end of the day is always an even number? So why is it only nine in total? " Junhoe questions

" So what you're saying is there should have been a total of ten people that went missing, but somehow the tenth victim wasn't able to be captured or escaped? " Haiyi answers.

Junhoe nods. 

" How confident are you? " You ask

" Honestly, it's the only thing we can hold onto right now. But before that, Jiwon has to make an announcement. " Junhoe says

Everyone turns to look at Jiwon. 

" There have been speculations going on that there's a mole in this department or the FBI. No one's sure if this is just some made-up lie or not, but still, I would like everyone to keep an open eye. " Jiwon states

" Are you sure it's not the FBI department just shoving blames at us again? " You ask

" We'll get to the bottom of this, but for now. Whatever that goes on with this case stays within the people working on this case understood? " Jiwon asks

" Yes, Sir. " Everyone responds. 

" Alright. Then I need all of us to split up and examine the locations where the victims went missing. Report back here by the end of the day for a conference. Adjourned. " Jiwon says

You leave with Haiyi and head to the first location. 

Santa Barbara

" Alright, so the victims are Kim Jisoo and Kim Jennie. " Haiyi says reading off the report. 

" So they were two of the many people that were here. If they were to go missing or if something were to happen to them, wouldn't people have noticed? " You ask

" It could be the case, but they could have also been too quiet because it's the beach there's a bunch of people. " Haiyi responds. 

You click your tongue. 

" But I don't believe that there won't be one person that would help them. What would make people refuse to help them? " You ask

Haiyi looks through the file and hands it to you to read. 

Both of you immediately head back to your car and drive back to the office. 

" Hey Donghyuk, just a question out of pure luck does your case happen to have a couple missing too? " You ask

" Bae Irene and Kang Seulgi. " Donghyuk replies

" Alright, I guess we'll be having the meeting much earlier. " You say before hanging up. 

" So we have Roseanne & Joy Park, the first two victims. Bae Irene & Kang Seulgi the third and fourth victims. Kim Jisoo & Kim Jennie the fifth and sixth victims. Wendy Son & Amber Liu, the seventh and eighth victim and Kim Yerim, the ninth victim but no sign of her partner. " Jiwon says as the pictures of the victims displayed on the whiteboard. 

" What could enrage the suspect or suspects to kidnap all these couples? " Jiwon asks

" It could be a hate crime or envy. " Donghyuk answers

" I have another thought. " Haiyi interjects. 

Jiwon tells her to continue.  

" There have been rumors the government is using pairs to experiment with something for the new trainees. " Haiyi states

" It could be why the FBI was quick to let us have this case. " Junhoe says. 

" But why would they let us have the case? " Jiwon asks

" I heard from Soohyun that it's kept confidential between the government that not even the FBI knows. But all she knows is she's been seeing new people that she doesn't recognize before. " Haiyi says. 

Jiwon thinks. 

" Alright, let's say we take that idea and run with it. I still don't understand why the government would choose these victims. " Jiwon spoke

" All we know is couples have a bond, and they would never let anything or anyone try to get between that bond. They're willing to kill or die for each other. " Donghyuk says. 

" What if they're soulmates? " You suggest

" With the amount of evidence we have gathered, it's possible. " Jiwon says

" Soulmates aren't able to proudly announce their love because most of them have either died or gone missing, so is it a surprise that it wouldn't be? " Haiyi agrees. 

" Alright. Then we'll split this case this way I need two
