Kill Me, Kiss Me

Kill Me, Kiss Me (K2-케이투-, "Kei Tu") is a Korean manhwa originally created by Korean author Lee Young-you revolving around two identical cousins of different gender who end up switching places for about one week's time. "K2" was first released in Korea published by Daiwon C.I. with the first volume on December 22, 2000, and later formed a total of five individual volumes by May 29, 2002. The manhwa volumes were distributed in English by Tokyopop between February 2004 and February 2005. Tokyopop radically redesigned the covers of the volumes from how they appeared in the Korean version. "Kill Me, Kiss Me" is published by Egmont Manga & Anime in Germany.
Plot.
"Kill Me, Kiss Me" is a story with two separate but loosely connected plots. The first, spanning only the first volume of the manhwa, centers around the high school girl Tae Yeon Im and her obsession over a handsome model named Kun Kang. Tae finds out that Kun goes to the same school as her cousin Jung-Woo Im, to whom she is almost identical in appearance. She makes a deal with Jung-Woo to trade places so she can get closer to the model of her dreams, though they settle on only one week for the switch. However, upon arriving at Pure Water High, she promptly gets beaten up by the gang member Ga-Woon Kim, apparently Kun Kang's closest friend. Despite this minor setback, Tae does not give up and goes back to the school the next day to continue her attempt to get closer with Kun. Most of the rest of the plot from this first story arc involves Ga-Woon starting to develop feelings of attraction towards Tae, though still under the belief that Tae is really Jung-Woo, Ga-Woon starts to question his sexuality.
The second arc in the "Kill Me, Kiss Me" series spans the rest of the manhwa from volumes two through five, and has almost no connection with the first arc. The story now concentrates on the beautiful girl Que-Min Ghun, who although appearing innocent at first glance is actually incredibly strong. She attends the same school as Jung-Woo and after meeting him one day in the street, starts to develop a crush on him, going as far as trying to protect him from people like Ghoon-Hahm Che and his gang, the Yi Won. Eventually, Ghoon-Hahm offers an arrangement: in exchange for not beating up Jung-Woo, Que-Min will have to go out with the gang leader himself. Ghoon-Hahm and Que-Min start their forced relationship, and Que-Min finally gets Jung-Woo to remember her name and notice her.
