They somehow share some similarities as both shows are involved with hostage-taking situation which took the part of thickening their plot. A lot of conflicts also take place in the setting that entail each of the characters' roles/stories in surviving every day they went through.

If you can't get enough of them (the OG squad), try watching the Japanese remake.

Same plot but different feels. You'll get a glimpse of early 2000's jpop culture and kawaii aesthetic kogal girls. Though the main characters were reduced, the casting was superb as the old and young versions have a huge resemblance to one another, making it more convincing and not confusing to watch. Also, there's a lot of dancing, and the ending here is not a cliffhanger compared to the original.

Enjoy (^._.^)
