tvN has released a making clip for the recently released 1st teaser of upcoming drama 'The Liar and His Lover', starring Lee Hyun Woo and Red Velvet's Joy!

Both the lead actor and actress are tasked with putting on an array of different emotions for their very close-up shots, from a natural, bright smile to a sort of sad, but hopeful smile.

While filming for the teaser scene where Joy is running late for a date with Lee Hyun Woo, she cutely complains that the guitar on her back keeps hitting her in the back of her head, and more!

You can watch 'The Liar and His Lover' starting March 20 at 11 PM KST!
