Yerin's pov

Since eunha died i retired as a detective, i need to seek revenge for the death of my sister, like what i said, im a retired agent, so it wont be hard to investigate and to fight since i have yuju - shes a doctor she sometimes helps me before when i got wounds from fights, she's also friends with eunha and willing to fight, she trained martial arts so she could also fight, and i have sinb -shes my girlfriend, shes powerful, trained karate, also willing to help, she's so smart, and sinb's father heechul - he's really powerful because of his business he's willing to help us, he helped us alot 

—

"Hey kids" uncle heechul called us

"Dad?, what're you doing here?"sinb asked her father

" yerin, please explain it.."

"We're in uncle's company , i helped him with some things then suddenly, 2 girls attacked uncle's guard, 5 out of 7 died"

"Only five?, i mean-"

"Yes, they could kill the other 2 but, they didn't thry just went out and we never seen them" yerin explained

"I guess, its the same people who killed...eunha" heechul said

"And my sister, jessica unnie"

"Sinb"

"Dad, i need to know why jessica unnie died, what if they're targeting our family since yerin and our family are business partner?"

"They could be the reason why you're jessica—"

"Then why didn't you killed them?" Sinb said raising her voice

"They're skilled"

"We could look at the cctv?"

"We'll try.."

"Btw, i might be in us for a week, i hope you find more evidence"

"Yes dad " yes uncle" they said in unison

—

"Yewon, i heard in news that youre back?" Sinb called yewon

"Y-yes"

" i hope you're fine now"

"Hmm"

" im really sorry for your family's death"

"Its fine, its not your fault"

"Hmm, since your back in korea why dont you meet my friends, its been 3 years, i know you've change alot in appearance"

"Maybe, btw i gotta go"

"Hmm, ok bye!"

"Yerin ah, i also want to investigate about sica unnie"

"I dont think your dad wants that"

"But...what if it has something tp do with eunha unnies death?"

"Hmm, lets see, but dont let your dad knows things about it ok?"

—

"Yerin ah, i think they're both girls, but we couldn't see them since its kinda bit dark, plus they're wearing caps"

"They're skilled, they beat those guys easily, are they psycho?

" dad said they might be the people who killed eunha unnie and might be the one who killed sica unnie, they wouldnt do that if they're in their right mind"

"Power"

"Huh?"

"People whose obsessed with money and power will do everything for it, they steal, they do hardworks , they can also kill "

"Its because our family's both rich and powerful"

" im wondering why they only beat those five guys? "

"About that, heres the info about them"

" they're old guards almost 3 years and a half in soumu's company, while the two are 2 years"

"So whats the deal?"

"I- i dont know, i dont know anymore..."

"Yoy should sleep"

"No, im fine, we could still find some evidence"

"Sinb ah, just sleep ok?"

—

"Yuju?, where are you?"

" im at home why?"

"N-none"

"Ok bye unnie"

"Hmm, so why did you came here?" Yuju asked

"Ahh, its about the thing happened earlier" yerin answered

"Yeah, sinb called me about it"

"Sinb will start to manage the company for a week since uncle's in overseas"

"Hmm"

" Can you not work and go with her and me?"

"I could do that"

"Thanks"

"Watch her every move, i think she knows something"

"Yes sir"

"Good morning mr Lee, im sinb heechul's daughter"

"Good morning too"

"Hmm, shall we start the meeting?"

"Yeah lets"

Just 5 minutes of the meeting they heard some noises coming from the outside of the meeting room

"Sinb, they're here again!"

Sinb knew who yerin's talking about , she hurriedly went outside 

'Who are they?' Sinb thought

They already attacked 4 guards

"Mr Lee, no!"

"I've been trying to find you Lee seungri"

"What are you talking about"

The girl got Mr lee by his neck and pushed him to another room

• ill go do the two girl aa girl A and girl B*

Sinb try to go near the girl A but the other girl B suddenly came into the scene and pushed her to the sofa, she then grab yerin's arm and pushed her into another room and put a table on it so yerin won't escape

Then she came back to sinb and inject something on her

And sinb felt her eyes heavy
