Woo-jin is a guy who wakes up in a different body everyday, regardless of age, gender and nationality. Sometimes he's a man, a woman, old, young, or even a foreigner. He's the same person on the inside, but on the outside he's always someone new. Looking at a different face in the mirror every morning is hard for him to get used to. Then, one day, he meets the love of his life. Woo-jin fell in love with Yi-soo at first sight, and Yi-soo accepts Woo-jin who's a bit special. He can withstand any kind of difficulties as long as he's with the love of his life. But, there are difficulties which can't be overcome with just love. This is an ordinary story where we feel butterflies and also conflicts over love. It's the new movie 'The Beauty Inside.'
