It's been five months since Seohyun last saw Jaejoong, she didnt know where he was but didnt want to ask her brother. Seohyun notice the change in Yuri when she around the two boys, one day Seohyun pull Yuri aside and ask her some question. 

"Yuri..do you like one of the boys?" 

Turn to look at Seohyun."Ho..why would i like them?" 

"Just tell me, i know you like one of them." she said with a smile. 

"No." she turn her back to Seohyun. 

Seohyun hug her."Yuri ah, if you love him, tell him..you don't want to lose him right. I know some girls that likes him too..if i were you, go tell him before he accepts other girl." 

Yuri turn around to face Seohyun."Who like him? If he goes out with someone else, i'm going to murder him alive." 

Haha. "Then go and tell him." 

"But..but..what if he doesnt like me." 

"You dont know if you don't try." push her away. "Go." 

Seohyun watch as Yuri walk away, she start walking back to her classes as well. She didnt get to see Yuri until lunch when she went up to her. Seohyun ask if she told him about her feelings when she shake her head. 

"Yuri..why didn't you?" 

"I couldn't..i got scared." 

"Yah..your so tough before..why scared now?" 

"Yah, it's different talking to girl then boys." 

"Look who coming." she said and smile. "Hi Jonghyun, Kai." 

"Hi." Yuri said. 

"What's up with you?" Jonghyun ask. 

"I think she sick." Kai said and give Seohyun some juice. 

"Yah..why do you always think i'm sick." 

"You two stop fighting with each other." Jonghyun said trying to calm Yuri down. "Yuri eat this apple." 

Seohyun looked at Yuri and smile."Kai, want to date?" 

"What?" Jonghyun, Yuri said at the same time. 

"I was planning to ask you that." he said getting shy.

"It's ok..since i already ask..so do you want to date me?"

"Yah, why are you two doing that now?" 

"Your just jealousy no one wants to date you." Seohyun said to Jonghyun. 

"There's many girls that want to date me." He said

Seohyun smile when she saw Yuri answer to Kai, both Kai and Jonghyun were surprise to see Yuri raising her hand. 

"I really like you Jonghyun..i always liked you..i just didnt know how to tell you." 

"Why didnt you just tell me straighforward."

They all turn their head to face the voice that just spoke, they all looked at each other with cold expression on their faces. Jaejoong came and took his mom away when she turn back to face them again. 

"What's going on with you and Yunho?" she ask.
