Inday Will Always Love You

Mary isn't your typical period drama heroine. She is awkward, anxious, preachy, full of facts, a terrible singer, overlooked by her mother and seemingly destined to an empty dance card for the rest of her life… until Mary takes matters into her own hands.

The series is about an incident that takes place when the owners of the boarding house called 'Guest Summer Palace', which breaks stereotypes, and boarders with secrets gather to find Lee Seol who disappeared 13 years ago.
