Jealousy Is My Middle Name (Korean: 질투는 나의 힘; RR: Jiltuneun naui him; lit.

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.

He likes having him around as he's the only person he feels comfortable with, which means he often takes advantage of Lee's passive nature, making him run errands for him all over town.

The fiercely independent Lee, however, works without complaint, having started a new relationship with part-time photographer/part-time vet Park Seong-yeon (Bae Jong-ok).
