Why is it Boys Over Flowers? Wouldn't it rather be Hana Yori Dango?
In any event....yeah, it is based off of Hana Yori Dango. However, I wouldn't recommend it unless you have a cold and time to waste. Subpar acting at best---Just as bad as Boys Over Flowers. <--Hence the reason it had no part II or a film. If you want a crappier version with a few less hours there is always FIVE:MENS5 <--- I'm dying through that one, but feel some weird sense of obligation. I lived for HYD; I was epically insulted by BOF; I'm periodically killed by FIVE!
If you're looking for an UPGRADED version of the above but with better acting I'd go to Thailand with the U-Prince series. Not to mention there you have 10 or so guys to choose from and they're all hot super hotties. I wish I was years younger (well fiction wise and spoke Thai) to attend this Uni---plus I love their uniform; I'd feel like I belong on Star Trek or someting!
Everyone has their own favorite list of U-Prince's. My top 3 are:
1. U-Prince: Crazy Artist <--- This is the tearjerker one. Everyone cries for this one!!!
2. U-Prince: Gentle Vet
3. U-Prince: Single Lawyer
They all have a girl (there is some BL action (3) in some of them). It has something for everyone.
I think we've all outgrown the 1 girl 4 guys series.
