Both have the famous woman and common man trope where ML in both series is a huge fan of the FL. I really enjoyed watching Love Scenery with all the cute moments between ML and FL. It is such an interesting story. So if you would like to watch something similar to A Beautiful Lie as it is airing, Love Scenery is a great pick.

Castaway Diva and He is Psychometric though have different focuses are great stories. Lee Seung Joon plays the deadbeat father in both series that causes the family to run away and hide their identities. In both stories this father plays a crucial role in the development/thought process of the characters and pushed them to who they are portrayed in each show. If you liked one, I highly recommend watching the other. There is also the element of romance and reunion between the main characters.
