after the incident with nickhun sungmin and kibum always pretends to be a couple when a boy tried to flirt with sungmin,they would imediately back off once they learned that she's kibums girlfriend(it's no secret that kibum can throw punches because he trained boxing) and so they are too afraid to mess with him same goes to girls that try to flirt with kibum (sungmin's piercing stare can scare them off not to mention those nunchucks that is always visibly tucked on her backpack),  

A day after her father annouced that they would be going back to korea

At lunch:

sungmin was feeling down,she's about to tell her bestfriend that she would be movig back to korea when a hand was placed in her shoulder,

"hey fake girlfriend,let's get lunch"

"haha very funny kibum"

"hey!you look down,what's bothering you?"

"i'll tell you later,let's eat first i'm starving!"

sungmin dragged kibum hand in hand(kibum smiled at their intertwined hands, and thought why can't they date for real)

after lunch sungmin sighed put her chin on her head thenlooked at kibum

"yah!what are you looking at?am i looking too handsome today?"

sungmin scoffed "you know what?i'll miss seeing that ugly face of yours"

"huh?but why?you know you can look at my face 24/7 since your my fake gf and all heheheh"

sungmin sighed again "we're moving back to korea,dad got promoted i'm transferring to SUJU high near my dad's new company ESEM"

kibum gave sungmin a blank stare

"Hello?mr.handsome?still there" sungmin waved a hand at kibum's face
