IU and Byun Woo-seok's countless kisses and the behind-the-scenes story of "Salon Drip" are becoming a hot topic.

The candid behind-the-scenes footage of IU and Byun Woo-seok's shoot has been revealed!
With even comments coming out about kissing countless times, it seems to be becoming a hot topic among fans as well haha.

This also makes you feel how important the chemistry between the two is in the drama *21st Century Grand Prince's Wife*!

Just hearing the story makes me look forward to the chemistry between the two actors, so I am curious to see what kind of scenes will appear in the main story.
