It was such a surprised to Yuri and Yoona this morning that some students have transferred to their school. Suho, Kai, Lay, Xiumin, and D.O is now in their school. Yuri just can't believe it. Moreover, two of them which are Suho and Xiumin are in her class. Suho sat beside Yuri and greeted her while Xiumin say just in front of Yuri, beside another guy on her class. Yuri was so surprised when the boys greeted her. Why? Because she was dressed like the usual her, the nerdy Kwon Yuri with glasses and some other disguisse. But she's kinda glad there's someone she knew here now and they're not gonna bully her or even ditch here. 

Suho, Xiumin, Yuri, Yoona, Hyoyeon, and D.O sat on one table during lunch in the canteen. "Well, guys so some of my friends have transferred to our school," Hyoyeon excitedly said. "I'm sure you guys still remember each other so I won't introduce you guys to each other again and blah blah blah whatever. And now, Yoona, Yuri you still remember what we told you yesterday?" Hyoyeon asked. 

The girls nodded, feeling a little bit nervous. "Well, you guys, including me are going to have a couple dance with three of the EXO boys. The battle is only 3 weeks away so we should start focusing on practice," Hyoyeon said, suddenly being so serious. Yoona who was seated beside Yuri just nodded. She wasn't as nervous as her older sister. Joining a dance competition is just for fun she thought. 

"So, today? After school?" 

FLASHBACK 

The music started playing and Hyoyeon and some boys started clapping their hands. Yoona started to move and laughed while Yuri just stood there. She obviously doesn't know what to do. Yuri ended up only move when she's moved by Yoona during her whole dance while Yoona completely have fun and showed some of her moves. Actually Yoona was a dancer too, she is. She dances Hip Hop. She actually joined a dance competition twice and won both of them as 1st place and 2nd. Yuri danced, but it was a very long time ago. It brought so much memory to her and she doesn't want that. She promised she would never dance again. But here she is, on a dancing room, with a Hip Hop outfit with the music beating. She wanted to move, she wanted to dance but it just doesn't seems right. Everything was coming back and she's afraid of the panic attack. 

But as one of the boys who was known as Kai started to guide her, she tried to fought back all the negative thoughts and painful memory. 

"I will dance again, Yoon.. It's okay to be selfish just once right?" Yuri asked inside herself and nodded and followed Kai's move. She was able to follow all even thought she has flaws. It has been 3 years since she had last danced and she was stiff. 

"So, girls, here's what I wanted to tell you earlier," Hyoyeon started as soon as Yuri sat back down and the praised from other boys are said. "I have cancelled our participation on the school's open house dance battle," Hyoyeon said but before she could even finished her sentence the two girls shouted 'what' right on her ears. "Wait, wait, listen. Instead we'll be joining a bigger scale dance competition. It's held annually and it's called the Underground Dance Championship. We have only 3 weeks to prepare," and with that the Kwon sister's jaw dropped.
