Both shows have a villain male lead created by a writer/cartoonist that comes to life
They both are romcoms

Same concept of a character popping out into the real world, female leads having to help them out and make sure they're not making a mess or being revealed due to their lack of identification.

Both have are writers/cartoonist and their "villains' come to life. Both are under the romance and comedy genre as well.

Chen Zhe Yuan plays the male lead in both dramas. The female lead thinks the male lead is a villain at the beginning of the drama. There is amnesia in both dramas. In Renascence the female lead gets amnesia when she hits her head. In Mr. Bad the male lead pretends to have amnesia to protect the female lead from headbreak.

In both cases FL is the book writer and ML is the villain and they fall in love. In "Fall in Love in the Book" FL enters in the book world. In ”Mr. Bad" the character gets out from the book to our world. "Fall in Love in the Book" is a class B mini-series but the plot is comprehensible for their 5 minutes episodes. "Mr. Bad" is a drama with 45 minutes episodes and there is more character development.

Both dramas have a writer FL and a ML who is the villain of her story. Both involve a sort of time travel (FL entering the fictional historical world vs. fictional historical ML entering the real world). Both couples are antagonistic at first.

Both FLs are writers whose historical novel is close to the end. Both MLs are the villains of the novels, who magically come to the real world.

Heartbeat love is a light and funny drama .
mr bad and heartbeat love both have
1. comic charater coming live .
2. destiny bringing them close to the writer .

In both, the leads live in apartments across from each other with side-by-side balconies. Both stories have the leads bickering and they're super cute together. The plot for both dramas is haters to friends to lovers. Both follow FL who start working in a new company and how they succeed in the workplace. Both stories have a main couple and side couple, all couples are pretty cute. Nice amount of comedy, and romance, and overall healthy relationship.

Both are dramas in which the MLs are from a comic book and the FLs are from the real world, and the two meet when one crosses over to the other's world.

Both dramas have an inverted premise - in MB the ML travels from a novel to the real world, in FL the FL travels from the real world into a novel. Both MLs are the villain of the story.

I would say this reminds me of Mr. Bad for the novel plot stuff… I wouldn’t say it’s exactly the same but at least both should be during their youth… as for the storyline I wouldn’t say too much just that they made it quite familiar yet not… still interesting to me
