The Beauty Inside (Korean: 뷰티 인사이드) is a 2015 South Korean romantic comedy film based on the 2012 American social film The Beauty Inside, about a man who wakes up every day in a different body, starring Han Hyo Joo.

His best friend Song-beck works with him, taking care of sales and going to meet Woo-jin's clients in person.

He waits until the right day when he is someone handsome (Park Seo-Joon) to finally approach her and ask her out on a date.
