Both have a character that sees dead people. Both deliver an eerie feel. The main difference is that The Village: Achiara's Secret is more of a campy Suspense Thriller and The master's Sun is a Romantic Comedy.

(in both dramas)The murder of a family member in their youth causes one of the leads to pursue a career in law enforcement.... they end up working on a case that connects to their own family murder...

Same writer for both. Choi Ho-Chul was the Winner of the "Excellence Award" at KBS One-Act Play Script Contest in 2012 for Secret/Secret Love. Mask is the second Drama written by this writer. Both are Drama/Melodrama/Romance. Secret was one of those dramas that you just couldn't stop watching, you just have to know what happens to these characters. Mask looks like it will be the same.

Same adorable lead actress, Both are fun romantic comedies with lead males that despite having a complicated and rocky relationship start with the spunky lead actress they fall for her. There is an interesting dynamic in both that put the actress in a position of power over the male leads early on. There is also a time in each that the lead male seems a bit emotionally dependent on the leading lady. the main difference is that HL deals with gangsters and DIL deals with bad marriages.

Both feature a cop that sees ghosts and uses that to solve crimes and then eventually a mystery concerning themselves. GSDCY is darker and more serious than WAY.

Both are romantic comedies and have a divorced and newly single moms. Child care is the reason the couple ends up living together. Both are sweet, light, and funny love stories.

both are romantic comedies that show a funny and sweet clash between traditional country clan life and city life, with a leaning toward preserving tradition.

Both: are comedy mixed with melodrama (although I think BotC is a bit more dark and KMHM is a bit more cornball), have people doing dirty deals to try to inherit money/power/family business, feature a sibling-like relationship between the leading lady and the 2nd lead male, have a mystery surrounding both the leading lady and the leading man, leading men have trust issues due to people always wanting to take advantage of them for money, are well done.

Both star leading actress Choi Kang Hee. Both deal with a social phobia that stems from a repressed memory and trauma. Both have adorable funny leading men and even more handsome 2nd leads. Both have tender moments and upbeat endings.

little girl detective is around school age and with the help of a bumbling young cop solves a crime related to her father's death/ Seonam Girls HS detectives are 5 girls in school solving crimes connected to the headmistresses family and other students. both include some comedy and are a little campy.

Both have a violent crime mystery going on in the back ground of a romcom type drama that causes you to suspect everyone until the final reveal,

Both MY SECRET HOTEL and MASTER'S SUN are Kooky Spooky Mystery, romance, and Comedy Combine well in both. Both have a leading lady with two potential suitors and at least one jealous obsessed woman trying steal the leading man.
