Sol do Mestre (2013)

Both leading actors and actresses give off the same vibe. Similar timid, innocent girl and arrogant, workaholic, obsessive heir. Even the development of the story and the relationship between the main actors and actresses are very similar.

Either ML/ FL can see ghosts and together unfold a backstory/ suspense
Kdrama has Rich ML CEO while Thai one isn't
Rom com Fantasy genre

Both are similar in the sense that the woman has a superpower but it does not work around the ML. Which is what starts the romantic interest for her in him, as she thinks he is special.

This drama even features in My Lovely Liar

A young woman has an accident and starts being able to see ghosts; she's as dishevelled and kooky as the female lead in the Mysterious Nurse; she also latches onto the male lead (though in The Master's Sun he's an arrogant jerk of a chaebol).

They both have a girl who has this strange power. And the power is connected to dead people. Both are really fun and enjoyable.

In both dramas the lead couples form a codependency bond as a result of lasting side affects from traumatic experiences, which leads to love. Both female leads turn into other people, one mentally the other physically and they both try to arrange the daily lives to hide and protect themselves from being found out. Both male leads are very rigid CEO's of family run companies in which family members and others are using any means to get rid of them, so they can take over the company. Both dramas have a very cute serendipitous second couple love story.

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.

Joo Joong Won is the stingy and greedy CEO of Kingdom, a conglomerate that includes a major department store and hotel. He meets the gloomy Tae Gong Shil, who started seeing ghosts after an accident. Their lives take a new turn as they work together to deal with the terror and sadness brought about by the spirits, while delving into a kidnapping incident in Joong Won's past. And unknowingly, they fell in love with each other

Both FLs are haunted by ghosts that disappear only when she touches/is close to the ML, and try to help the spirits resolve their issues that trap them on earth. Both MLs are initially cold and harsh to the FL.

They have the same Lead actor. In both dramas, So Ji Sub is a man from a rich family even though their attitude and their stories are totally different. Both of the drama genres are comedy and romance but The Master's Sun has a supernatural vibe to it as well. Superb acting and chemistry in both dramas ( even though So Ji Sub's acting has improved so much more in Oh My Venus)

Rich weird guy falls for poor, clueless girl. Rich Guy falls first and pursues her even though he keeps denying it. His behaviour is totally crazy that everyone who knew him wants to know if he went mad. He faces up to his feelings soon though, and takes care of his girl.

Both are boss-employee romance.

Overall, High-End Crush was sweeter, and more hilarious, with the male lead so confused and behaving abnormally.

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.

Both female leads are considered eccentric by the male leads for their ability to see ghosts or visions. Funny|Supernatural type with Romance.

Both dramas have supernatural aspect mixed with romance and comedy.

Ghosts theme is a main theme of two dramas. In both dramas one of a leading characters is able to see a ghosts. The seeing character in these dramas can protect themselves from ghosts by touching and being present with the other leading character.
