Steps by steps were taken with carefully by Kim Yongsun toward student's lounges of International Business Study. Sometimes she looked back at Byul who was hiding behind the wall near the entrance. That man observed her action and once their eyes met, he showed her the fighting gesture.

Letter and a red rose that wrapped with simple but beautiful wrapper which she brought earlier were being held tightly. Yongsun scratched her head. “What the hell I am doing? He is the one who supposed to do me a favour, not me doing him a favour. Damn it!” She mumbled to herself.

“Psstt..”

She held her head upright and she noted from behind the wall, Byul gave her a signal. Seen that other girl walked her step toward the elevator, she hurried her stances. The letter and the flower were hid behind her back. She cleared as to steal the girl's attention.

“Excuse me” The brunette hair girl turned to Yongsun.

“Sorry, am I?” She looked at Yongsun confusedly.

Yongsun nodded. “Can I speak to you for a minute?”

“With me?” The girl frowned her eyebrows when Yongsun nodded again. She stared at Yongsun from head to toes who wore big black shirt, loosed jean with black cap and sneakers.

“What do you want to talk about and do I know you?” She asked directly.

“Why he not give these by himself? I mean it better if he himself gives to me if he wants to get to know me?”

“He is quite shy”

“Alright, say thanks to him and I take this letter and flower.”

Yongsun nodded her head again and went back to Byul after Krystal walked away. She sighed deeply qt Byul who had a silly grin. Right after she stood in front of Byul, she smacked his head “!”

“Hahaha. So Yong, what is her name?” Byul asked eagerly.

“What the hell did you do, Byul-ah? How could you know which department she in but not her name? Her name is Krystal Jung.”

“Krystal....” Byul said while smiled like a crazy people. Byul side hugged Yongsun’s shoulder as to try to persuade her. “Let's go! I am going to treat you some ice-cream.”

He and Yongsun became best friend since their first semester at Seoul National University. During their orientation weeks, he and
