"Uhm, I'm sorry, I took your phone by accident when we bumped into each other. I would like it back," Amber said politely. 

"Yeah, I kinda figured. Well, since your on the plane, where are you heading? I'm going to Seoul," The stranger's voice sounded familiar to Amber, but she doesn't recall anyone. 

"I'm going there, too! I'll just see you outside the airport then," Amber said happily.

"Okay. Do you mind me asking who's this?" The stranger said with curiosity.

"I'm f(x)'s Amber. May I ask who's this?" Amber was wondering who this person was because she heard this person's voice somewhere. TV? Radio? She didn't know.

"Oh, well, I am S-" The stranger was cut off by a pilot lady, telling him to turn his cellphone. "I'll call you later," the stranger said and hung up. 

Amber was so furious, her knuckles became whiter. She doesn't know what to do how to get her phone without knowing the person was. Amber made a promise to herself that she will find that person, so she can get her phone back.
