At the bar,

Myungsoo sits at the counter of the bar with a drink while he is waiting for Sungkyu. 
Sungkyu arrives and gives him a high five. 
" Yo Bro ! What happened to you ? And where is your beautiful wife ?" He asked him with a smile
" Don't talk about her ! I just need you to accompagn me... I just need a drink !" He replied angrily
" Nononono ! Tell me what happened ? It's not anymore in your habit to call me for a drink !" He said with a punch on his shoulder
" Ouuch ! It's hurt ! What ? So I'm married so I can't have a drink with a friend ?! I'm Kim Myungsoo ! I drink when I want !" He yelled back
" Yaaah ! Are you crazy ? If you are in a bad mood, I'm going to leave ! I'm not here to let you speak to me like this !" Sungkyu argued 
" I'm sorry ! What do you want to drink ? I'm just mad, she makes me crazy !" He replied 
" The same as you ! Did you have a fight when you just got married ?!" He asked while calling the barman with his hand 
" Can I have the same as this young man ?" He added when the barman arrived
" Yes ! It deals with her company ! Everything is about her company, she only lives for it ! I was a tempory manager in their marketing department so I gave them one of my idea to a project and today a company menaced the Jung Company for plagiarism so she becomes stressed and cold. She has this cold attitude with me too ! While everything is under control, she is angry and very cold to me ! So we fought and I left her office !" He explained 
" I understand, you are mad but do you think that leaving her without a solution to your fight is a good idea ?" He asked 
" If I didn't leave, I don't know what I could say to her. I was so mad and you know when I'm mad I can say horrible things !" He remarked
" Yes, I do ! You two have a strong personality... But can you take her place ? Do you think that it's easy for her to be the CEO of this big company ? She abandonned everything to fulfil her Grandpa's wish and it's the only thing that he left her..." Sungkyu tried to convince him
" I know ! But I don't really like her attitude ! She is like a spoilt child ! Everything has to be perfect ! She is so cold !" He replied
" Yes, she is like this ! Is it why you love her ? You take her as your wife ever when you know it ! It's her and you can't change her ! She already stop her plan to destroy Hyuna, to leave her sister without anything ! But she realized that she loves you and doesn't want her revenge to eat her so she just left Hyuna disappeared !" Sungkyu said
" Yes, I forgot that... You are always right ! What can I do without you ?!" Myungsoo exclaimed by hugging his friend
" It's because I'm the older ! So have respect to me ! Finish this glass and go back to your lovely wife ! Make sure to apologise !" He gaves Myungsoo a gently punch

At their apartment, 

It's dark in the apartment, he thinks that Soojung isn't at home yet but when he switches on the living room, he sees his pillow and a blanket on the couch. 
He sighs and goes to their bedroom, he tries to open the door but it's locked. He realizes that she is mad and tonight he is going to sleep outside their bedroom. He decides to give her space this night so she can calm herself. 

As for Soojung, when she hears him trying to open the door, she is impassive and determined that tonight he is going to sleep outside. 
These days, she wonders why she feels strange... Her doubt fade rapidly because she has lot of work and is stressed by it. Her travel to Japan then to Jeju without really any rest make her realize that it's why. 

Myungsoo sleeps in one of their bedroom, he wakes up and goes out to find out that she already leaves. He sighs and prepare himself to go work. 

At the Kim Company, 

He directly goes to his office. He begins to work but he can't really be concentrated, he thinks that maybe he can send her a text to say to her goodmorning and asks her how she is. He send her
