Dora's Dream (2021)

Both dramas revolve around VR and at some point in both the characters must find their way out of the fake world.

Both FLs are being treated by doctors through VR and enter into a fake world. They must regain their memories or come to terms with their past in order to return to the real world.

Both are mini dramas involving one of the leads entering a dream-like world in order to help their mental health, with the other lead soon entering the world to help them.
