Yoko Kamio's "Hana Yori Dango" manga has captured the world that it had spawned Japanese, Taiwanese and Korean live action dramas. It was also copied by Chinese and now it will soon-to-be adapted into an American drama too.
She might have not expected that it will also start the foursome trend in Korean dramas (you can check out out dramabeans for more info) and variations of the monicker with totally different storylines.
Boys Over Flowers - The one that started it all in Korea.
A Gentleman's Dignity - Amidst the foursome and flower boys trend this drama upgraded their own and marketed the foursome as F40. Yup, flower boys in their forties.
Grandpa Over Flowers - It doesn't end there. The title gets an extra, extra upgrade. Move over F4 and F40, it's the Grandpa Over Flowers. It's a reality show of grandpas traveling in different countries.
Noonas Over Flowers - After the success of, Grandpa Over Flowers, the genders are reversed and we get the spin-off of Noonas Over Flowers. The women are in their forties and sixties. Not necessarily grandmas.
So what's next? F4 years old? F14? I'm guessing I will be updating this post in the future.
