Yus-Na: must be some hoe, prettier than me!!
Namjoon: ( starts crying miserably) it's..
Yus-Na: oppa why are you crying?? I can't see you crying tell me what the actual deal is? Who is he cheating with?
Namjoon: See-Hi!
Yus-Na: You must be joking right now oppa!! ( Starts laughing because she thinks it's a prank on her)

Yus-Na: See-Hi wouldn't do that to me!
Namjoon: They are!!!
Yus-Na: (starts to cry out aloud) tell me it's a lie! ( In utter shock)
Namjoon: no sis! I wish it was a lie! I caught them red handed in jins penthouse! ( Joon narrates the event to Yus-Na where he caught them cheating)
While Namjoon was narrating what he saw with heavy heart , Yus-na's heart was breaking bit by bit. She was in deep sorrow. She couldn't believe her best friend could do something like this to her.

(Yus-na's pov-
" See-hi... how could you do this do me. We were more than best friends, we were sisters.  You knew how much I loved jin and you still choose to do this. Why See-hi Why? So everything was lie. Your love for me..your love for joon Oppa, everything was just lie.  You were just pretending. I would have not cared about Jin. But you...you were my only friend my sister"
Yus-na's stopped Namjoon saying anything further as she had no strength left in her.).

Yus-na: Oppa!! please stop!!( putting her hands on her ears) how you are telling me all this. Doesn't your heart ache while saying this.
Namjoon ( All red and with teary eyes) : Yus-na, I  can't even explain what I'm feeling. But I won't let this anger and sorrow go. I won't forgive See-hi. I am telling you the truth and I told you, so you should also know what that woman is.
Yus-na: I can't keep it to my self. I am going to meet See-hi right now. I want answers. I want to know who is the real See-hi. Im leaving right now!
Namjoon: Yus-na I know what you are feeling. I don't want to give you more burden. But please don't reveal to See-hi that I know everything.
Yus-na : but you should confront her.( little confused)
Namjoon: some betrayals needs realization and they cannot be forgiven.( he said with straight face) 
Even Yus-na felt his dark orb.
Yus-na: okay.. I wont tell her anything. But I have a request Oppa.  She must realize how it feels when you break your dear person's heart.
Namjoon : SHE WILL...
Yus-Na: Oppa!! Take care of yourself!! And please don't be hurt!!! I'm going through the same as you are but maybe my pain is twice of yours! Gather your courage, I'm here with you as your sister at every step of life! I'm leaving now! I'm leaving! Bye
Namjoon: Yus-Na! Please be well! I'll be here for you too! Bye!
