I hear that while Byun Woo-seok and IU were practicing a waltz, there were even reactions asking, "Are you dating?" The atmosphere on set must have been really fun haha. I think it looked that way because the chemistry was so natural, even though it was just a practice scene.
Just watching the two of them coordinate their movements gives off a strong romantic vibe; they are such a combination. I think the reaction will explode even more when the actual scene comes out!
