The Night Beyond the Tricornered Window (2021)

Both of them have supernatural powers and uses them to conquer something. The protagonists has flashback of their past too.

Both are action packed and slow paced w/the development of the characters. Artsy and Intriguing, as well as the plot in where the two protagonist help each other solve a crime :DD

Zhang Jing Yi is the FL in both. The chemistry is natural. The relationship had depth. However, BEITD does not have a satisfactory ending.

Both are super similar in that one of the male leads is an exorcist who is fated with the other male lead, who can communicate with the supernatural or is a ghost themselves. The two leads have a comical relationship at first, which then becomes more serious as the plot progresses. In both movies, the leads are bound together by a contractual relationship of some sort.

Both are based off of BL manga, but have been turned into bromances for the movie version. Some of the characteristics are still noticeable though, such as a degree of possessiveness and long gazes, touches etc.

Both are very similar in terms of featuring the supernatural, ghosts, exorcisms (i guess) and bromance.

except from one being a movie and the other a drama. sell your haunted house is about 2 exorcists working together but they have different method they use to get rid of ghosts. both within the drama and between the movie and the tv show

both main characters help lost souls pass on by investigation. the main lead has power they don't quite understand and can see things others don't. which puts them in dangerous situations in which they have to figure a way out.

the male leads in both dramas see things they do not want to see with power they don't fully understand. although one is a movie and the other is a series both have a cop that uses the male lead to solve the harder cases.

both deal with curses and how to get rid of or deal with them. even use them to your own advantage
