Arranged Marriage with Kai

I need some answers

JiYun's POV
I woke up in my lovely bedroom with the sunshine hitting my face. Getting out of bed I rushed down to eat breakfast and it was all good and dandy. Today I decided to hang out with Sehun since it's been such a long time. He was going to come pick me up and meet with Baekhyun and Chen too. When I left the house, Sehun and Kai were waiting outside.

Sehun: you must be so happy with your husband out here too
JiYun: I'm actually not... so Kai what are you doing?
Kai: I want to spend time with you
JiYun: you had 3 years so no
Sehun: did you two fight?
JiYun: your friend broke my heart
Sehun: you little...
Kai: I'm trying to make it up
Sehun: man I wish you luck because you just got yourself an angry woman
Kai: I know that already
JiYun: he's not my husband anymore... we are just married under the law but I dorm consider him my husband
Kai: JiYun it's not as serious as you think
Sehun: did you cheat?
JiYun: yes he did and do you know what he did for her... everything that he did for me while we were dating! He clearly likes her and has more than just attractions... go to her! I'm not stopping you
Kai: I don't want her but you
JiYun: why me and not her?
Kai: your the one I married and promised to be with forever
JiYun: Sehun go one without me and I'll meet you guys in a few
Sehun: alright
JiYun: lets go somewhere

I brought him to the airport where we first met and he was smiling. The nerve!

JiYun: we first met and I didn't like you
Kai: me too haha
JiYun: you can't laugh
Kai: oh really?
JiYun: I'm mad at you
Kai: I remember every memory I have with you
JiYun: this is where we first met and this is where we will last meet
Kai: what?!
JiYun: I'm a little glad you didn't do anything too serious... or did you?!
Kai: I didn't! Or maybe...
JiYun: so you still have the heart of a playboy I see
Kai: she was very helpful at work which is why I was able to go home earlier than before
JiYun: anyways let's just separate for some time and tell your dad you can go back to work because giving you time off still won't change anything
Kai: he even wants me to spend time with you
JiYun: well I don't with an attempted cheater
Kai: I understand your mad so I'll give you some time
JiYun: thank you

I just walked away because talking to him just made me more sad and the fact that we went to the airport almost made me tear up. I went to see Sehun and the other two.

Sehun: how did it go?
Baekhyun: you got in a fight?
Chen: this is like your first one ever right?!
JiYun: yeah...
Chen: tell us what happened
JiYun: he... attempted...
Baekhyun: attempted what?
JiYun: cheating
Sehun: WHAT?!
Baekhyun: that bastard...
Chen: no wonder you look like the grim reaper took your soul
Baekhyun: whose the woman?!
JiYun: his secretary
Chen: what did they do?
JiYun: they eat dinner together, treats her very nicely like wiping her mouth and covering her skirt, he also let her lean on his shoulder

Then tears started flowing down my cheeks and I couldn't hold it in anymore.

Chen: don't cry over him... he may be one of our best friends but not anymore
Baekhyun: let's go spy on him
Sehun: make sure he's not cheating anymore
JiYun: it will just break my heart a little more
Sehun: but your not happy right now and divorce is a bit much if he only attempted it
JiYun: I don't want to divorce him but if he still is cheating on me I might have to and that's one of my greatest fears
Baekhyun: come with us!!!

All four of us decided to go track down Kai. They were actually able to find him fast I guess based on a friend radar. He was walking into a fried chicken place and then I saw that woman!!!! He still has the nerve to see her face.

JiYun: THATS HER!!!
Chen: WHAT?! She's not even pretty
Baekhyun: or attractive
Sehun: let's go in and investigate but not at the same time
JiYun: he already saw my clothes today
Sehun: here's a hoodie and some glasses... maybe tie up your hair in a bun

Then we walked into the place at the same time. We were at least two to three tables away. We just ordered chicken as usual and then tried to listen to the conversation.

Kai: we were found out
Secretary: oppa its ok

OPPA?! She calls him OPPA?!?!?! What the frick is this I'm hearing right now?!

Kai: your really cute and pretty... I hope another guy will meet you
Secretary: I only like you though and besides your wife might divorce you anyway so then we can be together
Kai: yeah that might be nice

THIS LITTLE...

Secretary: but oppa why did you get married so early? You should have stayed single a little while longer for me
Kai: but I actually loved her back then
Secretary: what about now?
Kai: I don't see her as much anymore and my feelings started dwindling
Secretary: it means your love for her was finite but for me it's infinite right?
Kai: yes it is but I came to tell you that I can't meet you anymore
Secretary: why? Is she following you? What's her problem? Isn't she a director too? Why doesn't she even work? And how do we know she isn't cheating either?

I couldn't bear it anymore and I just ate the chicken angrily. I chugged the beer down and went straight to the divorce center and got the papers. Sehun, Baekhyun, and Chen accompanied me and I was happy that they did. Luckily the two devils were still at the chicken restaurant about to pack up. I went up to them and slammed the papers on the table.

Kai: JIYUN! What happened?
JiYun: sign the papers now!!
Kai: what?
JiYun: you know what?! Give me your finger and just put it on this ink stamp
Kai: what are you thinking?!
JiYun: divorce or your not leaving and that girl
Kai: ok then... I won't sign it
JiYun: just sign it
Baekhyun: don't make her suffer anymore
Chen: I'm so disappointed with you and you cheat on her with that slutty vixen
Secretary: your disrupting business! Stop hindering our path and take this outside at least

I just ended up giving her a slap to the face and everyone was surprised at my sudden gesture.

JiYun: I don't want to hear from your dirty mouth! Kim Jongin!!! Sign this paper or I'm going to your parents! Pick one or the other! Why are you hesitating? Divorce me quicker so you can be with this vixen
Baekhyun: he won't sign it so let's go to his place
JiYun: alright! You missed your chance

I went out and left to go straight there. They weren't home so I had to go to the company to see my father in law. He was in a meeting and I had to wait only a few seconds before it ended.

Father in law: JiYun!!! What's the matter? Did Kai do something?
JiYun: I want to divorce him and he wants it too
Father in law: what?! Tell me clearly what happened
JiYun: I was actually willing to give him another chance but he met up with that vixen again and they actually want this divorce so they can get together
Father in law: that will never happen because I will banish her
JiYun: no need father in law... just let me divorce him
Father in law: JiYun!!! This breaks my heart that my stupid son would ever do such a thing! You were the daughter I never thought I would have
JiYun: I know father in law and you were also very good to me so maybe we can keep in contact
Father in law: I will beat him until he ends up in the hospital
JiYun: I'm sorry for shocking you about this and I hope we can end this now
