In both dramas the protagonists returns to the countryside/hometown. Each story is wrapped in a strong sense of community and the protagonists find a way to a "better self" in the warm environment the community brings.

Both are about characters in a comic changing their fate. Rewriting Destiny is Chinese well extraordinary you is Korean. Both are love stories with a sick female lead.

Both of the female lead were kind and then betrayed by close friends and loosed some people they love.

Both dramas focus on vampires and loving humans. Loving the interactions between wanting to love someone for an eternity and not being able to be with that person. Hopefully, love will stand the test of time.
