On the other side, two people were sitting in a cafe and enjoying the coffee. The cafe was situated opposite the tall building of Long Groups. 

"Thank you for accepting my invitation on such short notice," Long Jie said with a sincere smile. 

"You're welcome. Luck you, my schedule happened to be free this afternoon," Chen Yuling said with a light chuckle. 

While Long Jie ordered two espresso Chen Yuling stole the moment to stare at his beautiful face.

"Anything you would like to order?" Long Jie's voice brought her out of trance. 

"Umm?" Chen Yuling was at the loss of words. She was embarrassed no one affected her like the way he did.

"I said you would like to order anything else?" Long Jie repeated. He gave her an earth-shattering smile full of brighter teeth that had her heart beating against her chest like a ticking bomb waiting for exploding.
