Very different in plot but similar elements of ghosts and a sweet somewhat teasing relationship between the main characters.

Both feature ghosts, mystery/horror elements, and a strong friendship that can be read as romantic but doesn't have to be between the leads.

Both are short dramas about the FL caught up in a situation involving ghosts and meeting the ML who helps her.

While different in setting and plot, both have horror. mystery, and romance as the genres and feature a ghost that haunts the FL because he loves her or wants to marry her.

While very different in plot, both dramas have a ghost-seeing FL and a "unique" ML (he can chase her ghosts away vs. he can help her because he isn't human). Both have horror elements and a slow-burn romance.

Both are historical dramas with fantasy worldbuilding and elements. Both have a similar feel despite very different plots.

Lihim is a brilliantly acted love story, with Kaleb Ong and David Revilla at their very best, romantic, but not kitschy, it is the story of a true-to-life relationship that has ups and downs, and it is an outstanding production with respect to directing, editing, cinematopgraphy, and sound, and it has, like "Papa", a beautiful OST.
