Climax

Both drama are about morally gray people, rich political elites, greed, cheating, power struggle, corruption etc.

Both dramas have morally grey characters, a villainous female lead, a heavy focus on the entertainment industry, and they also both explore how far one would go to achieve their own ambitions/desires.

In a desperate attempt to revitalize his stagnant career, prosecutor Bang Tae Seop hatches an absurd, but daring plan: take down the mayor of Seoul by exposing her corrupt ties to Lee Yang Mi, the head of the WR Group conglomerate. Tae Seop recruits Hwang Jeong Won to serve as an informant and manages to convince Kwon Jong Uk, a WR Group heir with his own grudge against Yang Mi, to join his cause.

However, Tae Seop soon finds himself in a more complicated situation than he initially expected when he discovers that his wife Chu Sang A, a formerly-loved actress, may be hiding dangerous secrets from him.

Eve revolves around the untouchable world of chaebols and political elites getting revenge against them while Climax explores the ruthless battle for dominance and supremacy within the unforgiving arena of brutal politics. Both shows portrayed romantic relationships as a tools for influence, power, revenge and manipulation. The story thrive on psychological tension, betrayal, and intense emotional conflicts...

Revenge, Manipulation, Politics, Chaebols, Affairs.... Both story has very much similar story lines....

It's got the same eerie, rich feeling. However so far Climax feels like a sort of investigating series in a way whereas Remarriage and Desires is definitely more revenge. They both have similar plots like there based on more affluent families with a lot of influence and power.

They have the same eerie, mysterious feeling to it but have two completely different plots. However they are still based on rich families.
