Something is not right (1/1)

Finally, tonight is junior prom.Hyunseung said he will be picking me up at 6pm. Its one hour ride from my house to Hotel W, where the junior prom will be held. His text wasn't that long like usual. Maybe he thought a short text is enough since we will be talking to each other during the prom. I spent my morning with Gayoon. She was planning for Gikwang's surprise birthday party, although there still 3 months left.Its already 4 in the afternoon now. Gayoon and me were planning to call a cab to the salon which we already made an appoinment ealier. Then a kid, around 4 years old, walk to me and gave me a letter."Noona, here's a letter for you.""Okay. Gamsahamida, who gave it to me?" I was curious about the letter."I'm sorry but the person called me not to tell you.""Okay then. I will read it. Thanks again.""Cheonmaneyo," and he dissapeared from my sight."You think is that Mr. D's letter?" Gayoon asked me."I don't think so.""Let's open up and take a look."___________________________________________________________________________________________________________Hyuna, Walk straight to the park. I will see you there. Let Gayoon go to the salon alone. We need to talk about something. I think you know who am I. I will be there waiting for you. On the first bench when you walk in the entrance.See you soon.xoxo______________________________________________________________________________________________________Who the heck is that? How am I suppose to know who is the one sending me anonymus letters? You think what am I? Detective Conan or Doremeon who has random gadgets which can help in solving mysteries?But I still walk to the park. Alone.And when I arrived there, there's no one. I look around, why isn't it crowd or what. It's Saturday, parents usually bring their kids out for a small outing or enjoy their family day.Suddenly I feel someone pat my shoulder. When I turned.....Someone punched me the face and I smell chloroform.
