"Seohyun-ah!!" shouts Tiffany and the other friends

Seohyun turns and saw them running toward her. 

"Wae?" asks Seohyun

"Did you been invite?" asks Minah

"Invite what?" asks Seohyun

"To EXO's Christmas Party" Tiffany answers 

"Christmas Party? Haven't, wae?" asks Seohyun

"It's confusing, why did they didn't invite you meanwhile you're one of their best friends?" asks Minah

"Maybe they're too busy and forget me. It's okay, I'll celebrate Christmas with my family." Seohyun answers 

"Did you sure? Isn't it is too boring to always celebrate Christmas with your family?" asks Tiffany

"How should I do, it's already fate." Seohyun answers and takes all her book inside her locker

Suddenly, someone runs towards them. They face him and it was Lay.

"Hyunnie! Mian! I forgot to invite you! Nah, take this!" says Lay and gives Seohyun the card

"Haha, it's okay." Seohyun smiles and takes the card

She opens the card and saw, 'The most important guest, Kai and Krystal'. Seohyun shocked and looks at her three best friends.

"Yeah, they was the most important guest." Lay answers 

"Waeyo?" asks Seohyun

"Because they was the one who created the Christmas Day." Tiffany answers

"So, they was official couple, huh?" says Minah

Suddenly, someone, or two students come toward them. They was Kai and Krystal, she pinned her hands in Kai's arm. They four look at the couple.

"So, you guys was official already, huh? Congratulations then!" says Minah 

"Haha, gomawo" Krystal answers

"Yixing-ah, I think I can't go to the party. Just thanks to invite me" says Seohyun as she gives back the card to Lay and leaves the place

Krystal smirks and brings Kai away from that place. Seohyun goes to her class and quickly sits on her own seat. Her next, Luhan, asks her, "What wrong, Hyunnie? You seems angry"

"If you knew already I'm angry, then why did you keep asking me?" asks Seohyun 

"I'm just want to make sure.." Luhan mumbles and looks front 

Suddenly, he saw the official couple holding hand and get inside the class. Luhan knows that it'll make Seohyun heartbroken as he shakes Seohyun but she always avoids him. 

"Seohyun-ah! It's serious! Look at me!" says Luhan 

Seohyun still avoids him. Luhan quickly stands and slaps the table, making all look at him, also Seohyun. Luhan looks at Seohyun and then holds Seohyun's hand, making her stands next to him.

"Nobody can make Seohyun jealous once, because she's mine." says Luhan as he makes all the students shocked

Kai quickly released himself from Kr
