Jiltuneun naui him, (Jealousy Is My Middle Name) (2002)

Quiet, intelligent, solemn and recently dumped by his girlfriend, graduate student Lee Weon-san (Park Hae-il) takes a job at a literary magazine, ostensibly to supplement his income, but really to get close to the editor - the reason he’s now single. The editor (Moon Sung-keun), unaware of who Lee is, takes a shine to him and makes him his personal assistant.
