The characters are really different and the story is significantly different. BUT, the type of emotional feelings you get from watching are very similar. The drama between family members are very similar.

These dramas are very similar in tone, comedy, and theme. There are 4 siblings in each story and they are each trying to figure themselves out as people, professionals, and romantically.

Very similar plots! The con artists are trying to exact revenge and get justice in their own way, warping the justice system to ensure the bad guys get what's coming. Personally, I like Player better, but Switch Change World is still very enjoyable!

The beginning atmosphere of He is Psychometric is similar to While You Were Sleeping. The balance in humor and tragedy was also similar. The fantastical abilities were another shared similarity - reading into the past vs. into the future to solve mysteries in the dramas.

The plots are not exactly alike, but the tones and the tragic type of stories were similar. The workplaces were also similar. The flashbacks the MMCs experienced were also similar.

Both of these dramas involved an arson case that set the plots in motion. While the overall settings/workplaces are not anything alike, their are similarities in the characters and their outcomes toward the end that are very similar. The tones are also similar.

Both dramas have very similar tones - not serious, but not overly comedic either. The stories *are* completely different, but the romances are both equally sweet. Her Private Life is a more mature watch though (the hottness and sexiness level is higher in HPL ;D). Both are fun dramas about unlikely, but adorable romances.

Both dramas have fluffy romances with no huge, larger-than-you, villain/antagonist. The romances in both dramas are sweet and innocent. Both leave you feeling happy and optimistic.

I think Bring It On, Ghost was better than Oh My Ghostess, but if you absolutely must watch a drama with ghosts, humor, and someone stuck in between the mortal and ghost world, they are comparable.

Very similar tones and adventures. Plots are very similar. Balance of comedy/cuteness are also similar between dramas.

Both dramas revolve around heavenly beings trying to protect humans on Earth.
Please Come Back, Mister is not really a romance, but the comedy and tropes are similar.
They both have mystery components and executing the will of a higher being such as God and fate.

The plots are not necessarily similar, but the comedic moments are reminiscent of each other. Also, the 2 female MC's are similar in temperament to me. These dramas focus on different times in one's life, but the tone and atmospheres are similar. And they both leave you with a satisfied happy feeling once completed.
