both are a highschool slice of life coming of age drama with cute puppy love, and both have a little dance/cheer leading theme that brings the different types of kids together to work as a team..

this is kinda like the 3rd charm, meeting over and over in span of 8( while TTC is in 12) years, but here they only spend 12 nights in total of the 3 stages...

both stories are about the 2 main leads meeting in different stages of their lives, a story of first love, second chance and the last meeting..

both have the "cold rich male lead with a traumatic past", and they both have a mature/grownup ish romance.. with a strong female lead...
also, the parents in both dramas are more supportive than the usual romcom parent ;p

Busted is played in a wider more flexible setting, but they have had some "escape room" games as well..
The Great Escape is played in 1 "house/set" per episode, with several different "levels/rooms"..
both are fun mystery solving clue finding interactive games..

both The Great Escape and Crime Scene are mystery solving gaming show. in Crime Scene they look for clues to find the "killer", and in The Great Escape they use the clues to escape the different themed sets..

The Ghost Detective and Cheo Yong s1 &s2 are both similar because they are about ghosts and detectives that deals with supernatural cases..

The Ghost Detective and Who Are You are both similar because they are about ghosts and detectives that deals with supernatural cases..

Right from the beginning they seemed similar, both have the same main plot of time traveling, they're both cute, short and refreshing as well...

While I was watching Montage, I was reminded of Memory by how they both lost there kid in an accident and the heart ache they felt when the statute of limitations was near...
Granted they are different in a lot of things, but both are so heartbreaking...

Both are about a mother trying to save their child from a kidnapper...
