Both are mini dramas with the same ML. Beloved of a Lifetime has an easter egg in Love Behind the Mask by appearing as a story told by the FL in an episode.

In both plots, ML is much wealthier than FL, but they become closer due to the unique plot point. (Body Swaps/Pretending to be a Robot)
FL is hardworking, works in a more unusual field, and is generally relatable.
Secret Garden has quite a lot of mean interactions, both between the leads and with other characters, while I'm Not a Robot is a bit kinder/more heartwarming. Both romances have an "us against the odds" aspect.

It has somehow similar vibes:
- ML hates people that lie and people that doesn't keep promises.
- FL has a secret that no one knows.
- Trust and trauma are two main themes.
- Both of them are developed in a club. In City Of Romance, it is developed in a Comic Club while in Live On, the story is developed in a Broadcast Club.
