It's amazing that the advertising slots for *The Grand Prince's Wife* are sold out even before it starts! Haha.

All advertising time slots for '21st Century Grand Prince's Wife' were sold out well in advance. In a situation where the entire broadcast advertising market has been shrinking for several years, the fact that all advertising slots were sold before the show even aired is attributed to "the buzz surrounding IU and Byun Woo-suk and the high expectations for the show."
