They are both office romance dramas.
Leads do have some kind of a connection from the past in both dramas (even tho it's a different type of connection... hm... no spoilers~)
Both are light hearted and cute~
Female lead is that kind of cheerful, cute, a little annoying girl (I didn't like the female lead in Introverted boss but i liked the one in She was pretty)
The male leads... Well, they aren't really similar in any way i think but they still remind me of each other idk why XD
