Jo In-sung
Later that year, Kim worked with Noh for the fourth time in "It's Okay, That's Love", a romance that explored mental illness, starring Jo In-sung and Gong Hyo-jin as a mystery novelist and a psychiatrist, respectively. Kim called it "a necessary drama," saying he wanted to break away from the traditional genre of a medical drama/romantic comedy by making "It's Okay, That's Love" into "a hybrid" that puts more weight on breaking the social prejudices toward the minority groups. Kim added, "Ms. Noh, the writer, has the seriousness and the weight and I have the lightness and mass-friendliness. Together we make a great synergy. [...] I personally found it hard to keep the balance between a rom-com and a conventional (melodrama). Every one scene would contain both features. So long as this balance stays unbroken, the drama will be close to perfection."
