For both of these specials the piano is the main subject by which the main characters get involved with each other.

Same kinda vibe, but this is a bit campier........................................................................................

Both have a testosterone driven male seeking FL in the workplace................................................................

Both short stories that center around a ghost & a non-ghost...................................................................................

Both stories involve a ghost seeing female lead. "My Chilling Roommate" comes in movie (1 hr 52 min) or drama series (10 ep @ 15 min = 2 hrs 30 min).

Both are short stories that involve a person who is alive, living with ghosts............................................................

Both have a FL who can see/talk to ghosts. "Oh My Ghost" has a Korean version that is good too, but I preferred the Thai version better.

Both short stories that center around a ghost & a non-ghost...................................................................................

Both involve a love triangle in which the 2 girls are/were BFFs.............................................................................................

Same theme of school age kid attending school despite his limited time to be alive. However, My Friend is Still Alive has some humor in it that makes it feel less serious than Goodbye Summer.

An older guy, a car accident, memory loss, a young FL to assist w/ML's recovery journey & a happy ending.

Both feature a female ghost who refuses/is stuck in an apartment. Also, all the other inhabitants are fearful & want to leave. Difference is movie is much more light hearted.
