Gi Kwang ran to school roof when he finished his dance class with Ms. Kim. He wanted to meet his lover, Tiffany. Gi Kwang bought a white chocolate which was used to be Tiffany's favourite chocolate.

"Sorry, i'm late.", said Gi Kwang while sat beside Tiffany who was reading book.

"It's okay :)", Tiffany said while smile.

"Nahh, take it.", Gi Kwang gave the white chocolate to Tiffany.

"Wow, white chocolate! Thank you dear.", said Tiffany happily.

Gi Kwang was so happy when he saw Tiffany happy.

"Happy Birthday!"

"Thank you."

 While they enjoyed chatting, Gi Kwang suddenly silent for a moment. Tiffany looked Gi Kwang with a weird expression.

"What's wrong with you, Gi Kwang? Is there any problem at home?", asked Tiffany.

"No, i just wondering how soon if we're separated."

"Hia, we won't be separated! I promise!", said Tiffany as she raised her hand up and maade a swear. Gi Kwang chuckled when Tiffany made an aegyo.

"If one day we will be seperated, don't cry okay? Promise me that you won't cry." Tiffany sighed as she've heard the words came from Gi Kwang's mouth.

'Oh, I hate that words. Please don't say like that', said Tiffany's heart.

"Hmm, okay.", answered Tiffany.

 After celebrating Tiffanny's birthday with Gi Kwang on the roof top, Gi Kwang did not came to school for two weeks. No one didn't knew what is the reason. Tiffany confused.When she asked his bestfriend, Du Jun just shook his head.

"Gi Kwang, what is going on with you? Where are you? I miss you.", said Tiffany to herself.

Seo Hyun also helped her searching for Gi Kwang. 

"Seo Hyun, where do you think he is? If he not come by this week, I will give up searching for him. I'm tired.", said Tifany to Seo Hyun who is reading novel.

"Hmph, sorry Tiffany. I don't know where is he. I've searching for him all over the place and I already asking his friends but they shook their head."

"Maybe I should stop searching for him. Yeah, maybe this is the best way."

"Don't give up Tiffany. I know you miss him so much. Tiffany doesn't know 'give up' word, right? Maybe he has a reason why he did like this."

Suddenly, someone that she knew came into the class. Other students in the class look him too. He came inwith Du Jun.

"Good morning, Tiffany!", greeted Gi Kwang.

"Ah, good morning!", replied Seo Hyun represented Tiffany who was dumbfounded.

"Tiffany, what's wrong with you? are you okay?", asked Gi Kwang.
