First let me say I love Kdramas. I can also see where a Kdrama focusing on a lesbian couple is going to be an uphill climb. Aside from censors and societal mores there is the writing problem. Many Kdramas have at least two strong and well written male roles. Bromances abound as well as love triangles containing two men to one woman
I’m always thrilled if the FL is written well but too often she lives in a vacuum where other women are concerned. Unlike real life where women tend to form strong relationships with other women (mothers, sisters, friends, lovers) and depend on them FLs rarely experience that depth of female character development and much screen time with a significant female character, not like you see with male characters.
So to write two strong, well developed female roles, where the romantic relationship is focused on them—-that’s a real challenge. Korea is certainly not alone with this drama problem. I’m happy to see there is more freedom in Korean cinema.
