The Beauty Inside (2018)

Han Se-gye (Seo Hyun-jin), a top actress shrouded in mystery, has a secret she can't tell anyone: once a month, for a week, she transforms into a completely different person, regardless of gender, age, or race. One day, Han Se-gye gets caught up in a fatal scandal with Seo Do-jae (Lee Min-ki), the director of a preferred airline. The seemingly perfect Seo Do-jae also harbors a secret: due to a past accident, he suffers from prosopagnosia (the inability to recognize faces). A fairytale-like romance unfolds between the man who is the only one in the world who can recognize Han Se-gye, and the woman who can only be her true self in front of him. This heartwarming drama embraced hearts weary of external conditions and others' gazes, delivering the message, "No matter what you look like, you deserve to be loved." If you want to experience both delightful laughter and a heartwarming afterglow, I highly recommend binge-watching it!
