Korean adaptation of this drama. The same premise with more of a cohesive direction. I wouldn't call it an exact 1:1 remake as aspects of the story have been changed.
1. They travel time through car accident.
2. Time travelling exposes the real murderer.
3. Intriguing but not frustrating.
4. You'll crave for lead character's chemistry and love it.
Both are about survival game with one mastermind.
3Nen has a really great theme it focuses on, it is about bullying. It is a really good japanese-style-dark comedy and full of life lesson.
365 is a really suspenseful, similar to manga Btoom.
Both dramas are crime show where people get a second chance to fight against their destiny, thanks to time travel. Both dramas are hard to predict and have twist plot.
