Early next morning after the 4 woke up, the Park Sisters told them that they are going to Lee Mansion that day. Mr. Choi already dispatched some of his men to the mansion while his son Seunghyun with Jiyong and Taeyang is guarding Chaerin's Dad. When they got there, Bom told Dara to tell them the plan

"Okay girls, i want you to listen to me, i'm going to tell you some important things about our plan to capture Mr. Shin and his son" Dara told them

"Mr. Shin is behind all of this, Unnie?" JB asked, Dara nod her head

"Why? Do you guys know him?" Dara asked them

"No, i'm just asking Unnie.." Minji hit JB's head and told her to keep quiet and ask questions after

"Okay as i was saying, Mr. Shin is is the mastermind of your Uncle's murder. He knows something about him that can lead him behind bars. I won't tell you what it is,  it's better for you girls not to know anything"

"So what's our plan?" Chaerin asked, Dara looked at her, she remember that she promised Chaerin that it will be she and her against them

"Sorry Chaerin but i can't keep my promise to you.." Dara said, Chaerin look at Bom then to Dara

"We can't risk your life girls, you already know that.." Bom said too

"But we can help you, Unnie's. You taught us how to fire a gun.." Minji said

"Yes but that's not enough, you saw how many they are.." Bom answered

"You made a promise that it's you and me against them!" Chaerin said looking at Dara

"Chaerin i--" Dara didn't finish what she's going to say, Chaerin walk out of the library and leave her 3 cousins with them

"She's worried about you, Dara-Unnie.." Ryo said

"I know that but this is our job and it's not right that we will let you girls come to us in this mission." Dara explained

"We understand that Unnie.." JB said, Dara look at her sister

"You better talk to her. You will be leaving in 45 minutes.." Bom said

Chaerin/Minji/Agent C.M's room

Chaerin is so pissed, Dara already promised to her that she will let her help them but she didn't kept her promise. She wants to be with her all the time, when they took her Chaerin thought that she'll never going to see her again and she won't let that happen anymore, she let out a deep sigh and heard a knock on the door

"Chae.." she heard Dara's voice but she didn't look at her

"Can we talk?" Dara said again still Chaerin didn't move a bit, she's still looking at the window

"I know your mad at me because i didn't kept my promise to you but i hope you understand that this is part of our job.." Dara explained

"You said you let us help you.." Chaerin said

"Yes i said that and this is the way you guys will help us. Just stay here in the house, i already told you guys where i hide the other disc and that will be your
job.." Chaerin didn't respond

"I'll be back Chaerin, i promise you that.." Dara added

"What if they do something bad to you or they will kill you?" Chaerin asked

"They won't do that.."

"How can you be sure?" Dara sigh, she walks towards her and spun her so that Chaerin can look at her

"I'll be back and i want you to wait for me. I won't let them do anything bad at me." she said looking straight to Chaerin's eyes

"Don't go, please.." Chaeri said and hug her, Dara is surprised

"Please send someone to do this job, not you Dara please.." Chaerin beg, Dara's heart had been torn apart, deep inside she's scared too specially that Dong-jun might not let her go alive but she has to do this

"Nothing's going to happen to me, believe me when i say i'll be back for you.." Dara said, she hug Chaerin tight

"I Love You Chaerin.." she said and broke the hug and left the room

Bom and Seungri is preparing Dara's things, they put on her a tracking device and a tiny camera to monitor her whereabout and who's she's talking to. Dara received a phone call from her Oppa that he'll wait for him in the abandoned building again in Gyeonggi-do before Dong-jun come back from his trip to Japan. She brought with her the disc

"Are you sure you want to do this alone?" Bom asked her sister

"Yes Unnie, if i'll get in trouble, you know what to do.." Dara said, Bom hug her tight

"Be careful okay and keep your promise that you'll be back.."

"I will Unnie, don't let them leave your sight okay.." Bom nod her head

"Good luck Noona, some of our agents will follow you to make sure you'll be okay.." Seungri said, Dara gave her a small smile

"Seungri go upstairs and help Daesung guard those girls.." Bom said

Minji's room...

"You really want to go with her huh?" JB asked her cousin Chaerin, they were sitting on Minji's bed while Chaerin is looking at Dara's car while some men put some of her things inside

"Yes i want too.." she answered

"Your not scared to die?" Minji asked her, Chaerin shook her head

"I don't care if i die, as long as i'm with her and she's with me.."

"I told you she really loves Dara-Unnie.." Ryo said to JB and Minji while Daesung is just listening to them

"Daesung-ssi, why don't you let Unnie com with Agent C.M?" Minji asked

"It's too dangerous for her.." Daesung answered

"She knows how to take care of herself, Daesung-ssi.." JB butted in

"Please let her come with Unnie.." Ryo pleaded, Daesung shook his head then he saw Seungri came in

"So whatcha girls doin'?" he asked

"Nothing, just trying to help Chaerin-Unnie be with Agent C.M on this mission.." Ryo answered

"You can't because Bom-Noona is downstairs, guarding the door.." Seungri said with a smile then JB and Minji look at each other then a smile appear on their faces

Dara look at Chaerin's window for the last time, it's hard for her to do this but she has no choice

*I'll be back Chaerin* she said to herself and get inside her car and drove away

Bom went upstairs to check on Seungri and Daesung and what are the 4 girls doing. When she opened the door she saw, Daesung and Seungri playing cards while Minji, JB and Ryo is watching TV

"Where's Chaerin?" Bom asked, Minji points the door of Agent C.M's bathroom

"She's been crying from the moment Dara-Unnie left.." Ryo said, Bom walks towards the bathroom and knock

"Chaerin, what are you doing there?" Bom asked but Chaerin didn't respond

"Open the door!" Bom said and bang the door hard

"Leave me alone!" Chaerin answered, Bom look at the 3 girls and the 2 boys playing cards

"Chaerin come on, you know that you can't come with her but she promise you that she'll be back right?" Bom said

"I said leave me alone please!" Bom sigh and walks towards the door

"Try to make her come out of that bathroom guys.." Bom said to them

"We will, Unnie.." JB answered

2 hours and 30 minutes later..

Dara saw the abandoned building, she took her binoculars and tried to look if someone else is there besides her Oppa, when the coast is clear, she step out of the car and went at the back to get some of her things. She opened the door and look at some guns she have, she place 2 .45 caliber on her back, her knife on her side and some magazines on her pockets. She remove her boots and change it into a comfortable one then she throw it at the bags inside

"Ouch!" she heard someone said, she grab a submachine gun

"Who's there?!" she said while pointing the gun at the bags but she heard no one then one of the bags move

"Stand up slowly and show me who you are!" Dara shout then slowly she saw a head peeking on the bags and her eyes got big at what she saw

"You've got to be kdding me!!" she said
