"I wish I can have her back" 

Flashback ( on the day itself - Christmas) 

"I'm going to draw for her!" Kris starts drawing professionally *Everyone knows his the best*
"I've decorate the christmas tree, is it nice...? Will she like it...?" Xiumin stare at the three he decorated
"Is this nice? I've bought a couple ring for her!" Chanyeol asked Baekkhyun as he kept smiling
"Kris gege!!! Is my coat nice?! I don't know!!" Tao messed up his closet to find a proper coat 
"Suho hyung, I've compose a song for her...and I'm going to make it into a CD and give it to her.. come listen to it!" Lay starts playing the piano
"Luhan hyung, I've picked out some flowers for her, is it nice?" Sehun showed Luhan the flower 
" D.O hyung! I've bought her a puppy.... isit cute enough?" Kai cuddled the puppy 
" I'm going to give her a beauty product" Xiumin starts choosing with Chen (natural republic)
" I'm so going to bake her favourite cake.." D.O starts baking
"I'll just write a letter and a small mystery gift..." Suho starts writing (sorry I've got no idea what he put inside the box...)

All 12 members went to the park their girlfriend asked them to go... 

They all waited for her. 

30 mins
1 hour
1 hr 30 mins 

she haven't come. After 2 hours of waiting, Sehun's girlfriend came first. 
Her face had a expression that Sehun couldn't understand. *why is she not smiling? Is she sad? Or do she not like the flowers?* 
"Oppa, I'm sorry... Let's just.. take a break ok?" with that she left.. Sehun stood there not knowing what to do. He soon realized she's gone. The love story between them is no longer going to continue. With that, sad and heartbroken state he went home. 
It all happened all 12 members, is this ... coincidence? 

AT EXO's DORM-

"Why did all of our girlfriend part with us...?" Lay asked as he continued to comfort the crying suho. "Molla..." Luhan who is trying hard not to cry.
" Maybe we didn't cherish out relationship properly..." Sehun concluded. "Le..Let's turn back time... please..." Suho begged 

With that everyone agreed, they went to prepare again. Everything
