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) has been married to Jin-hee (Jo Mi-ryung) for three years, but the stress of not being able to have children is taking a toll on their relationship. Rocker-boy Byung-ho (Fany, Over the Rainbow) is divorced and has one child, and he is currently facing 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 infidelity, divorce, blackmail and more landmines of love and marriage!
