Are Lee Hyori’s entire family and relatives also straw flowers?

I’ve been hearing rumors for a while, but now that I look at it, the sisters at Hyori’s B&B have also come down to Jeju Island and are living there.

He also owns the building and land of the sundae restaurant run by Lee Hyo-ri’s aunt, and when I looked through the article, I heard that he purchased the land as an investment at the recommendation of his father. I wonder if that price went up that much.

At this rate, I wonder if Lee Hyori is really a straw flower. If that’s the case, won’t my parents be able to cut it?
