Both have "older woman/younger man" trope ..........................................................................................................

Both dramas have fluffy story and little to no heavy conflict........................................................................................

Both dramas give me the same vibes. Fluffy, strong friendship, and little to no heavy conflict........................................................................................

-Smart and hardworking FL
-Supportive ML
-Both main leads work in the same industry
-Housemate
-Both dramas are lighthearted

Similarities:
-ML is a fictional character but suddenly turned out to be a real human on FL's birthday.
-Both are fantasy dramas

Both female leads are strong characters. They have electricity super powers. When I first time watching 'Fall in Love', it reminds me of 'May Who?'

Both main leads have insomnia. In Girl Next Room: Midnight Fantasy, it's the female lead who has insomnia. But in My Neighbour Can't Sleep, it's the male lead.

Both have detective work, strong female lead, smart male lead, and secondary couple. Both FL and ML solve the case together with their friends.
