The Night of the Comet (2019)

I know it's a bit early but this is the first drama that came to mind as I started watching this drama. Both contain parallel world travel. Protagonists live different lives in one compared to the other.

Somehow these 2 drama has that same emotional feeling when you watch them. Main male lead enters different parallel universe that leads him to encounter the female lead by accident. Male tries hard to change female leads outcome in the future and protects her from any possible death that may occur. Female lead tries hard to hide her feelings from male lead due to confusion in their starting relationship. Male lead tries hard to make female lead recall of the past before he runs out of time to be with her. Both has sad ending, not a happily ever after love story and seems to have continuing seasons that connects more stories.

Meet by window shows the parallel world and same in the night of the comet male lead travelled back in parallel world. Both are heart touching love story.

It’s basically a remake except the night of the comet 2 has a happy ending and the plot is different. The only thing similar is the alternate universe concept!
