For me, I think they are kind of the same when it comes to plot and the motives of the FL. In Fall In Love, she wants to find the truth behind her brothers death and her parents separation. While in Maids Revenge she misunderstands that the ML is the one who killed her father and she wants to find out the truth and the culprit. They're both set in the Chinese Republican Era and it has to do with conspiracies and political plots for both dramas leads to entangle.

Both are crime, detective, and undercover police work.
In both of them ,both lives are somewhat destroyed by a specific drug task force. They both lose someone dear to them. Like in this one he loses his fiancee, so he wouldn't put her in danger. But she's still intended to look for him and make him turn over a leaf, not realizing he's an undercover cop.

Look forward to this drama.
Both are in the gaming world, and in this one she catches the elite game leaders attention, but she's made a vow not to have any romantic feelings for someone in the same field as her. After much effort what will become of her vow? Can she avoid romantic entanglement?

It's also set during the communists era. This one has a ML that appears as a traitor in his countries eyes, but he's actually a communist spy. Like autumn cicada they are both undercover agents. They are both caught in a dangerous and complicated situation.

In Dugu the family was persecuted while in Weiyoung a marshal from the Chiyun clan was driven by greed and turned her entire families clan into a bloodbath. Which forced her to survive on her own. Like Dugu who is independent and strong, Weiyoung is the same, she is able to avoid all the enemies evil plans to harm against her.

After these two meet, she is able to gain wisdom, and was finally able to find peace for her family while finding love at the same time
