Depicting a boy and a girl platonically living together then falling in love (with cohabitation at the time a taboo topic in the South Korean mainstream), the series was a success, especially popular among teenagers and those in their early to mid 20s.

[1][2][3] Jeong became known for her cheerful and positive image, and in 2004 having starred in her first film, the romantic comedy He Was Cool alongside Song Seung-heon, based on the internet novel by Guiyeoni.

On February 10, 2007, Jeong was found hanged with a bath towel in the bathroom of her boyfriend's house in Samseong-dong, Gangnam District, southern Seoul.

[5][6] Her boyfriend, identified by his surname Lee, said he took Jeong back to his house because she got drunk while socializing with friends at a nearby bar in Cheongdam-dong.

[7] Lee, who discovered her body at 7:50 a.m. and called the police, said the actress had been recently depressed due to a lack of work, the imprisonment of her previous manager, and malicious attacks on the Internet about her physical appearance.

Although no apparent suicide note was left behind, Jeong had posted her thoughts on her personal blog on Cyworld just a day prior to her death.
