A few days later,

Every morning and every night, Myungsoo and Soojung call each other. She is very happy that he chooses to stay with the boys while she is aboard so he won't be bored. Everytimes, they call each other, they are so sweet that you can't stand it and want to kick them. 
The Infinite boys love to about Soojung but they quickly regret it because Myungsoo can be very very annoyed and is a prankster. 
They are in the living room and play video games, when Sungkyu thinks about something.
" Yaaah guys ! Next week is going be Myungsoo's birthday, so let go to the club tonight to celebrate it earlier !" He announced 
" Why ?" They asked
" Then, Soojung isn't here and we can have a boy party ! If we celebrate it, next week, Myungsoo would like to take her too ! He can't live without her !" Sungkyu argued 
" Yaaaah ! My girl isn't a burden and right she has to be with me !" He said proudly
" Sungkyu is right ! It's been a long time that we went to club only between men ! And Myungsoo, Soojung doesn't forbid you to go to club ! She says you to have fun with us !" Dongwoo added while Myungsoo sighed
" So, who agree ?" Sungkyu demanded 
Everyone raise their hand and Myungsoo doesn't have any choice. 

At the club, 

Myungsoo looks bad and seems not enjoy the night. His mind is filled by Soojung and nothing else. 
" Let's drink ! Happy pre-birthday !!!!!!!" Dongwoo said and everyone made a toast 
" Alright ! Tonight, I won't come back home guys ! I think that the girl in the red dress is going to be my partner !" Sungyeol declared with a smirk 
" Yayayaya ! We come here to celebrate Myungsoo's pre-birthday ! Not to hit on girls !" Hoya yelled with a serious look
" It's okay ! Sungyeol do it ! I don't care ! Have fun !" Myungsoo replied 
" Waaaaah ! You are the best !" Sungyeol shouted and went to the girl
" What are we going to do with him ?! Let's drink " Sungkyu said while shaking his head
