Ok just hear me out, hah! Nietsche ALSO has a love interest who has/develops a strong degradation kink for the ML. The ML in Kono Otoko has a similar masochist/degradation/humiliation kink, obviously, but more on the physical side.

Similarities:
~Both have famous male leads and common female leads
~Initially both the couples had love-hate relationship
~Both the series encounters and deals with entertainment industry problems.
~Last but not the least, have pretty much same vibe with different storylines.

While CR is written during the China Republic And. ILMPTHP is set in modern times I feelthe characters are very similar. A strong dominating ML with a weak FL that comes from hating him to loving him. While the ML changes from cold hearted to deeply caring and protective.

Both focus on adults/young adults and portray LGBT relationships in a more realistic, non-fetishized way, touching on real issues and portraying real lives (or as close to real as a drama can get).

Both dramas take place during Japan's emperial rule over Korea, and are packed with intrigue, humanity, sacrifice and love. Different Dreams is set in the 1920s, while Gaksital is set in the 1930s.

good characters, good fantasy, thisi story not too strong, good moving cameras, plots is not boring

both dramas follow the ups and downs in the daily lives of a quirky comedic family.
both nice light watch dramas.

Both shows pit the ML against a cult:
>> In SM the ML is trying to destroy a religious cult and save one of his classmates (the FL).
>> In Voice 3, the ML discover the mastermind behind the serial killers from Voice 2, who is aiming to groom new serial killers.

>> In Voice 2, both the ML and the FL discover and try to take down a cult/group of serial killers.

Both show basically have the very same plot but with my family is watching siblings are the ones looking at the love lives of their brother or sister.

*Both are tragic love-stories
*The romance is really slow in both dramas (especially "Song Rao")
*Both male leads suffers the loss of a loved one
*Male leads wants revenge,but the ML in Song Rao quickly gives up the idea
