In the video, the two reportedly showed off their perfect chemistry even while making different choices on questions like "Joseon King vs. Hyundai Chaebol." IU laughed honestly, saying, "Being a king is such a difficult position," while Byun Woo-suk gave a heartwarming response, stating, "We can complement each other's shortcomings." Seeing these two with such explosive chemistry makes me look forward to the drama '21st Century Grand Prince's Wife' even more, and I think I'm going to fall for Byun Woo-suk's charm all over again.
