Introduction
“The Beauty Inside” is a 2018 South Korean romantic fantasy drama that reimagines love, identity, and acceptance through a unique and heartfelt lens. Based on the 2015 film of the same name, the series stars Seo Hyun-jin as Han Se-gye, a top actress with a life-altering secret — she wakes up in a different physical form once a month, taking on the appearance of another person, regardless of age, gender, or nationality.
Her path crosses with Seo Do-jae, played by Lee Min-ki, a brilliant airline executive who suffers from prosopagnosia (face blindness) — a condition that makes it impossible for him to recognize faces. Ironically, Han Se-gye is the only face he can recognize.
As the two navigate their unusual circumstances and grow closer, the drama explores themes of inner beauty, vulnerability, and the true essence of love beyond appearances. Supported by a strong ensemble cast, including Lee Da-hee as Seo Do-jae’s sharp-tongued sister and Ahn Jae-hyun as a kind-hearted priest-in-training, The Beauty Inside delivers a touching and whimsical love story with a twist.
