While the plots are different, Sakurai Sho plays in both of these dramas as very similar characters. Both characters are eccentric and have very similar mannerisms and catchphrases (Iiii neeee~ vs Nantsutte~) and both have dark secrets they are hiding. If you liked Sho's character and acting in one, you will enjoy him in the other.
Both are dramas with the same kind of psychological game show format where people have to face themselves and their true selves are revealed to the public. Both involve a complicated connection between the characters that is revealed over time. They also have the same kind of pacing and the villains remind me of each other.
