Solar room fill with silence that morning. She looked so focus sitting on her study table. It's really rare to see Solar facing a book. Suddenly she broke the silence.

"Arghhhhh!!! Why so difficult",Solar sratch her head and bang her head on study table. 

"This question is really hard to solve. I really hate this subject. Why do I need to take the quiz?", Solar groan. 

Someone knocked Solar room door. Moonbyul enter the room with a tray on her hand. She walk approaching the stress girl. She can sense Solar gloomy mood even from her back sight.

"Is that question so difficult? I can hear your voice clearly from outside",she say and placed the tray she brought besides her boss  .

Solar didn't give any reply. She's not in a mood right now. 

Moonbyul smile. Moonbyul take a chair from make up room and she put it besides Solar.

"Let me see it.", she attempt to take Solar book but stopped by Solar.

Solar lift her head and stop Moonbyul from taking her book. "I don't want. I can solve this". She guard her book really tight.

"Let me see it.", Moonbyul try again. She pull the book softly.

"Aniya! Shiro! Hajima! ", this time Solar bring her book to her chest and hug it tightly. Didn't give any chance to the latter to take her book from her.

Moonbyul chuckles by Solar. "Wae?"

"Don't laugh", Solar said annoyingly. Moonbyul sound like she teasing her for not compatible to solve the question.

"Okay, Okay", Moonbyul bring her hand mid air indicating that she'll not disturb her. She rose up from her seat.

"I bring you this. Drink when you tired. I'll be there", she pointed at the white couch located not too far from Solar study table.

" Just call for me if you need anything. Anything means ANYTHING. Okay?". She finish her words and leaves Solar alone.

Moonbyul read a magazine that she took from under the table in front of her. Sometimes she will took a glanced at the one whom currently studying. Her mind back to last night incident where Mr.President asked her for help.

YESTERDAY NIGHT(FLASH BACK)
