One month later,

Everthing is alright in their life. Nothing really change since they got married except that their companies become more and more important and they are very busy. 
Myungsoo learns to live without controlling Soojung and she learns to make time for him. 

At their apartment, 

"Babe ! Don't forget tonight we have Sungkyu's birthday party at Hoya's parents restaurant! Also, I can't fetch you because I have an appointment outside of Seoul..." Myungsoo reminded her
" I know ! Anyway, I need to buy his present !" She responded
" Why ? It's not necessary ! He is already old !" He said 
" Bad friend !" She hit him 
" What ?!" He grabbed her and tickled her 
" Okay okay ! Go to work, you are going to be late !" She told him with a severe face
" Arasso President Jung !" He replied by kissing her and left the apartment

At the Jung Company, 

She is in her office and on the phone with Woohyun.
" Soojung aah, how are you ?" He asked
" A little tired and a little nauseous but I'm okay and you ? " She answered 
" I'm fine, just Sulli who drives me crazy with her craving ! Are you pregnant ? Don't kill me ! I didn't say anything ! Anyways, I call you because I have a problem with a project.." He said with a sigh
" Ahaha ! Fighting ! I can't wait to meet your baby ! I'm going to spoil him/her ! We don't have time for a baby ! Later but not now ! So what happened ?" She demanded 
" Don't dare ! I don't want him/her to become like my brother ! Well, you already work with Choi Minho ? He is never satisfaited with what we proposed him ! I really have a headache with him ! I don't know how you can collaborate with him ! He is so meticulous ! Can you help me with him ? I know that you're busy but I really need you ! In two days, I have to present him a new idea" He responded desperate
" Okay, no problem ! Send me everything by email ! Oooh, I have to go buying Sungkyu's present, I will go the shopping mall during the lunch break so I can work on your project later and you will have a wonderful project to present ! But you have to make a excuse to me, I'm going to be late thanks to your project and Myungsoo will kill me !" She told him
" Yes ! Mrs CEO Jung ! My baby bro is not a problem for me ! So deal ?" He replied
" Deal ! See you tonight Mr CEO Kim !" She laughed
" See you later ! Bye ! " He said before ended the call

At the shopping mall,

She also decides to buy a dress so she won't have to go back to their apartment to change for tonight. 
After she buys Sungkyu's present, she looks for a dress, she bumps into someone.
" Ooh I'm sorry !" Soojung said 
" It's okay but wait are you Jung Soojung ? Nice to meet you !" She responded by offering a hand shake
" Euuh, yes ! But sorry, I don't know you..." She replied and refused her hand
" Oh yeah my bad, I'm a friend of Myungsoo Oppa from New York, I saw him last time at the club with the boys, it was a fun party !" She said with a smile
" Really ?! So nice to meet you ! I think that it was a boys party.." Soojung declared with a cold face
" They didn't say anything... I hope to see you later and can you remind him to call me ? See you soon !" She said goodbye and left

Soojung is very mad, Myungsoo didn't tell her about this girl, who is she and why she calls him "Oppa", she takes the dress and goes back to the company. She doesn't want to make conclusion before talking with him so she decides to be concentrate on her work and Woohyun's project. 
When it's time to go to the party, she changes in her office, she is late when her secretary knocks at the door.
" Mrs President, we have just received it for you. It says that it's very important and that you need to look at it now..." Her secretary said 
" Ooh really ? Can you put it on my desk ? I'm going to look it before leaving. Thank you! " She replied 
" Yes, ooh you are really beautiful ! Have a nice evening Mrs!" Her secretary complimented her 
" Thank you ! You can leave, see you tomorrow !" She responded with a smile

She goes to her office, looks the enveloppe and sees that the sender is anonyme... She is curious so she opens it... and then she falls on her chair with tears. She doesn't believe what she just sees. It's Myungsoo with the girl from the shopping mall, they hug each other and ever kiss at the club but also near the supermarket. Her world collapses, more she looks at the picture to be sure that it's not Myungsoo, more it hurts her. She realizes that it's really Myungsoo, his clothes, his posture, his face, etc... She can't take anymore, she cries very hard before decides to go to confront him at Sungkyu's birthday. 

At Hoya's parents restaurant, 

Everyone have fun and wait for Soojung. Myungsoo begins to complain but his brother says that Soojung is late because she has to take care of a very important project for him. 
She arrives in tears at the restaurant, the staff are very shocked, she walks in a fury to them. 
" Ooh Soojung ! What happened to you ?" Hoya asked her shocked
" Babe ! Why do you cry ?" Myungsoo approched her worriedly 
" Don't touch me !" Sh
