FL in MLL can hear other people’s lies as they talk whereas FL in GWIA has the ability to make rich guys who are liars/cheaters to fall in love with her after looking into her eyes.

Both are about one of the leads having the ability to hear people's thoughts, resulting in them becoming somewhat jaded with the world.

First of all, Both give a similar vibe with how the character were written to be. Both shows plots are a ridiculously scenarios. Both shows main leads have to figure out how to coexist and eventually they find that they enjoy spending time together. I don't know if it's just me but I think since they both are from the same network company maybe writers or producers from one show worked on the other show, making them very alike.

Other Similarities:
Both Female Leads are strong, hardworking, quick witted women.
Both Male Leads are misunderstood in the beginning and overtime learn to be understood.
-It's still too early to say that the ML from wedding impossible is misunderstood but I think he acts out but he's intentions are different from what the FL sees.

Characters have special powers in both shows. They use their powers for their own gain at first but eventually learn how to use them to help others. They lose their powers at some point. Some characters aren’t what they seem.

Both dramas are mystery/thriller genres with a FL who has the supernatural ability to hear when someone is lying.

In both shows, ML is hiding his identity and keeping a low profile due to incidents in his past that receive criticism, even though he has achieved fame/success anonymously.
Healing vibes are really strong in both shows and they are both comfortable autumn watches.

Both feature a once superstar level male lead brought low by an event in the beginning and the mystery around that event.
