Quote from Bona
Bona revealed, “If the opportunity arises, I’d like to take on the challenge of a historical drama. I really enjoy watching fantasy historical dramas or fusion historical dramas in my everyday life, and because it’s a genre I’ve never tried before, I’d really like to try it at least once.”
