Although this is a parody, here the female lead is also a 21st century woman working behind the scene in the film industry, who transmigrate in an matriarchal universe. There she is in the body of a monarch who possess an harem of about 30 men.

Zhao Lu Si plays the main female lead in both.
In both dramas she travels through time to the past in a way. She's a little more clueless in Love better than immorality in my opinion but she still makes it work.

Both are heartwarming, funny, family dramas with a strong mother-daughter relationship. They show what it means to be a mother as well as the sacrifices that mothers make for their children.

Although many theme are similar but plot of AOL is totally different
Dr. Cutie is more light drama & miss chemistry between ML & FL whether else AOL is high budget with great chemistry...

[rebirth] and [love is more than a word] are both historical dramas that feature gay romances (however the lgbtq+ genre was expressed to a lesser degree in [love is more than a word] than [rebirth] since [rebirth] had telling cut scenes)
