Weather reporter Kim Hyun-woo (Moon Chae-won) is known for her beauty and elegance on television, but off-screen, she drinks and swears a lot. Hyun-woo has been friends for 18 years with Kang Joon-soo (Lee Seung-gi), a mild-mannered elementary school teacher who gives too much of himself in his relationships but always ends up getting dumped. Joon-soo has secretly loved Hyun-woo for years, but she claims she doesn't feel any sexual attraction between them, and he's had to stand by and watch while she fawns over married colleague Lee Dong-jin (Lee Seo-jin) and goes on a blind date with nice but boring photographer Yeom Hyo-bong(Jung Joon-young). Fate turns out that the childhood friends are destined together.
Love Forecast began filming in July 2014, and the shoot wrapped on November 9, 2014.
