Both dramas have the same feel, although the plot lines themselves are different.
In terms of similar vibes, both have a more mature feeling than other Cdramas out, where the main leads value and respect the others opinions. There is also a huge factor of community in both dramas which is refreshing. Both dramas have many side characters and plots that drive the story. Although both dramas have different plots, nothing "major" per se happens in either drama, both are more slice of life about modern people trying to earn a living, succeed in love, and generally live a great life.

same actress, and both stories about modern women in the work field!

Both drama's focus on a womens ambitions in the work world, but also are super good, heart felt slice of life dramas that teach important lessons

Both shows about law firms were the lawyers blur the line between good and evil and seek justice in their own way in their own way. Both FL and ML of each show are badass and have vendettas, goals they want to obtain, and must mutual team up with the other lead to fight the common enemy. Both shows are witty, the romance is their but not overtly, it's more of a push and pull/ sparks fly dynamic.

Both female leads only show their "beautiful face" to the world, but the ML sees them without their cover. Really similar themes of beauty with vs appearance.

Both dramas focus on "cold" but secretly caring male bosses and sweet secretaries/ helping FL. Both dramas are have an office romance where the FL has a special bond with the boss or something only she possess that keeps the relationship close, or in other words, the boss needs to keep her close because she's of use to him. The ML are really similar character types, straight to the point and truthful, but have a special place in their heart for the FL and do cute secret things for her.

Both involve office romance between a girl and three or more men who are vying for her affection in comedic and sweet ways. Feel good, warm, happy dramas that you can watch over and over again

Both are university romantic comedies. The male leads are extremely similar: both have very sweet, nerdy, quiet, cool male leads who unwaveringly love the main lead in a very sweet way although they can be oblivious to the female mind and dating dos and donts (in a very enduring way). The MF is also fun to watch and are both trying to figure out their place in the world. At the end of the day both dramas leave you feeling warm and bubble, although can be easily forgotten.

the plot itself of "top star going to a tiny village full of lovable characters for whatever reason and learning the true meaning of life/ getting back to his roots" is identical

Both are historical dramas with fun female leads to watch and really attractive main leads who IMO both have great chemistry to keep you invested. Also both have annoying side characters but nothing to drastic to keep you from watching

While both plots are completely different, the feeling the shows invoke is highly similar. Both have absolutely adorable couple scenes and extremely nice refreshing male leads

Both revolve around office politics and romance. Both are a great mixture of clever, cute, serious, funny etc. etc.
