"Ma'am, thank you for waiting," the post office secretary said on the phone. "Ms. Jessica Jung did not leave any forwarding address at her previous residence."   "Thank you for your help. Goodbye," I breathed a sigh of relief. Well, that takes care of that.    It was the day after the rather dramatic occurrence at the ChoSun Hotel. I submitted my resignation letter at Bobbi Brown earlier that morning, but my boss refused to accept it, saying she'll do what she can to reassign me to a different area. I wanted to hug her right then and there, but we were immediately swamped by a group of customers from Russia who wanted to stock up on their makeup. After that, my boss let me off early, and since I had no calls from clients, that left most of my afternoon free.   I didn't want to stay at home, pout, and wallow in my sorrows. I wanted to do something - anything - to keep my mind off a certain someone.   I mean, he didn't even try to stop me when I felt the penthouse! And what's with bringing me to the Bean and Bagel for, anyway, when he's got Poison Envy for a fiancee? Is he trying to get me in trouble? I thought he's supposed to be smart!    Seriously, the more I think of Kyuhyun Cho and his questionable motives, the crazier I think I'm going to get. So I did the best thing I thought of at that moment. I decided to investigate the murder case further.   -----------   It was around 5:00 PM when I finally tracked down model Chelsea Vaughn Lee's residence. It was located on a quiet street lined with light colored brick townhouses. Ms. Lee's home was indistinguishable from the rest of her neighbors' save for the gold "604" attached to the white picket fence and the flower boxes filled with pink and purple petunias under the front windows.    I stepped up to the picket fence and pressed the doorbell. Soon, the front door opened and a plump older lady stepped out.    "Yes, what is it, Miss?" she asked, wiping her hands on the white apron she was wearing.   "Anyeong! Does Ms. Chelsea Lee live here?" I asked. When the lady hesitated, I took out a makeup brochure and waved it. "I'm a Sales Representative for Bobbi Brown Cosmetics. I'd like to introduce Ms. Chelsea Lee to some of our products and offer free samples."   It was then that the willowy model stepped out herself. She was wearing high waist jeans, a sheer white chiffon top, and black pumps. Her hair was fixed in a neatly done fishtail braid that fell past her shoulders.    I crossed my fingers and hoped she didn't recognize me. I tried to put on a semi-disguise - curly hair extensions and thicker eye makeup complete with false eyelashes and winged liner.    "Did you say free samples?" Chelsea beamed. "Come on in!"   ---------------   Some fifteen minutes later, we were settled in Chelsea Lee's living room. She was seated comfortably on a cream colored settee and was allowing me to redo her makeup.    "So you're the famous Ms. Chelsea Vaughn Lee. What an honor to be here," I gushed as I brandished a Long-Wear Brow Pencil. "Everyone who's anyone in the industry has been talking about you lately."   "Really?" Chelsea's eyes sparkled. "What are they saying?"   "That you used to go out with Tyler Kwon and that he made a mistake of dumping you," I lied. I finished reshaping her left brow and started to fill it in with the pencil. "Almost everyone I talked to agreed that it was his loss, letting you go like that."   Chelsea laughed awkwardly
