After lunch, they took a stroll back to Sapphire.

"Don’t you feel tired working in a hotel? You have to face all kinds of guests every day. You should feel quite drained, right?" Dong Xian asked.

"Of course I feel tired." She answered "Mr Dong Xian, do you know what is the daily room rate of Sapphire?"

"The daily room rate is higher than our monthly salary ... we face all kinds of customers every day and we take a bowl of noodles that cost only 60 won for lunch ... moreover, we cannot express any trace of anger in front of guests. " Zhen Yin uttered on "We will run all round trying to meet the guests’ demands. In addition, we usually do not receive any compliments or thanks. " "However, we have pride in our job. This is professionalism!"

Dong Xian asked, "Don’t you feel the injustice? … I mean when you realize that other’s daily room rate is higher than your monthly salary?"

"The answer is ‘yes’ initially, but ‘no’ now. As I realized that these guests have their lives and I have mine. Moreover, no matter how much money they have, they couldn’t buy the happiness I experience and feel." Zhen Yin smiled at Dong Xian.

They have reached Sapphire.

Dong Xian stopped and looked at Zhen Yin, while her words still linger in his mind. "What is the definition of happiness?", he asked himself.

Zhen Yin is still smiling at Dong Xian. There is charm in him. There is something else - a kind of unexplained loneliness often reflects through his eyes. She felt increasingly tense as he kept his glance on her. "Is this the first time you visit Seoul? There are some travel brochures on Seoul at the front desk. Are you interested to make use of them?"

Dong Xian nodded, "Yes."

"I shall bring the travel brochures to you later", Zhen Yin answered.

Zhen Yin ran back to the main building. Halfway, she turned to Dong Xian, "Thank you for the lunch!"

He smiled. It has been rather uncomfortable in the small restaurant. Ironically, he felt great. He has lunch with her.
