Honestly, BOF is unique on its own, so finding an exact drama to compare is just impossible. But yes, there are some dramas with the same "Boys Over Flowers" feel, such as:
1. You're Beautiful - A love story of three popular boys and one poor girl. The vibe is exactly like BOF.
2. Coffee Prince - A girl working in a coffee shop while pretending to be a boy.
3. The Heirs - A high school setup. High school romance with a simpler plot, but top-rated actors.
4. Flower Boy Next Door - A sweet and romantic comedy with a lighter feeling.
There you go. These are some of the dramas that I know.
