At the warehouse, 

Soojung is very exhaused, she doesn't feel well and is very tired psychologically ever if Hyuna doesn't inject her the drug anymore. 
She begins to regret her argument with Myungsoo and thinks about their moments with tears. 
Hyuna arrives in the room and begins to laugh 
" Don't cry Baby sister ! Just enjoy your last time in this world with me !" 
Soojung glares her and doesn't ever reply to her
" Why ?! Do you think I'm going to let you live ever if Myungsoo chooses to divorce with you ?! Ahahaha ! Never ! Never you're not going to see the sun anymore !" Hyuna added 
" I don't think about anything more ! You are just crazy ! I don't know how we are sisters !" She replied
" We don't choose our family ! I'm going to send you to our dear Grandpa !" Hyuna said madly and left 
Soojung just lies on the bed with tears again.

Outside the warehouse, 

Hoya and his "guys" follow the man who delivered the package to Myungsoo so he finally knows where is Soojung but before calling everyone, he needs to be sure that she is here. 
He orders his "guys" to explore it discretly and is waiting for their information. He doesn't need to wait longer when he sees Hyuna goes out to give something to one of her guard. He concludes that if Hyuna is here, Soojung is here too.
Immediately, he calls Sungkyu because he knows if he calls Myungsoo, he will not think and only react by his mood. 
" Sungkyu ! I know where is Soojung but it's very dangerous ! There is everywhere guards and we don't know if they have guns or anything else !" He said 
" Ok ! It's already a good thing that we know where she is ! Don't do anything ! I'm going to inform everyone and call you back ! " Sungkyu replied happily

At their apartment, 

Everyone listen to Sungkyu's phone conversation with Hoya. 
When he hang up, Myungsoo looks at him with full hope.
" Okay before doing anything ! Listen to me, Myungsoo ! Hoya already knows where is Soojung but it seems very dangerous !" Sungkyu said calmly
" So what we are waiting for ?! Let's go !" Myungsoo began to take his thing
" STOP ! We need to think about a plan before going here ! We don't know anything !" Woohyun interrupted 
" But ..." Myungsoo tried to speak
" Mr Chief ! What do you think ? Hoya is already over here and looking at everything ! " Sungkyu asked the Police Chief
" Okay ! Give me every informations he has and we are going to move over here ! But Mr Kim Myungsoo, you have to promise me that you're not going to do anything without my consent ! " The Police Chief answered
" But how can I stay still without doing anything ? Soojung is over here ! She needs me !" Myungsoo replied anxiously
" I know but you have to promise it ! If you don't, you can't come with us !" He talk strictly 
" Okay
