Cartoonist Chul-soo (K-drama superstar Ahn Jae-wook, Star in My Heart, Goodbye My Love) wishes to avoid marriage, and why not? His mother was married three times, and he's perfectly happy with his irresponsible single lifestyle. However, an ill-timed one-night stand with Young-hee (Seo Ji-hye, Over the Rainbow) leads to an unwanted pregnancy. Meanwhile, sleazy divorce lawyer Min-ho (Gong Hyung-jin) can't conceive with his wife (Jo Mi-ryung), and resorts to multiple affairs. Jimi Hendrix-worshipping rocker Byung-ho (Fany, Over the Rainbow) is divorced and has one child, but when his girlfriend (Park Hye-young) becomes pregnant, he faces yet another marriage death sentence. Where exactly does love fit into all of this?

Based on a comic from Hur Young-man (who also inspired The Grand Chef), I Love You follows three intertwined couples as they wrestle with adultery, unplanned pregnancies, divorce, blackmail and more landmines of love and marriage!
