Both these dramas tell the story of the relationship between the ML and the FL in online and real life. It is the ML who discovers their online friendships first after making issues for the FL offline and then try to make up for it.
Similarities:
* Both MLs are "smart" and end up rejecting FLs school paper that prohibits her from graduating.
* I think both MLs end up falling harder in the end
* No ugly or messy love triangles.
Differences:
* In "Fall in Love With a Scientist" the ML has had a crush on the FL for a long time, so he falls first and takes the initiative in the relationship. In "Perfect and Casual" the FL falls first and later the ML realizes he likes her.
* Perfect and Casual has a contract relationship, and they live together. FILWAS does not have that trope.
