Both dramas are fluffy love stories involving a ML that is pretending to be a playboy while secretly quite serious. FL is competent and knows martial arts and is investigating who was responsible for death of family members in the past. Both dramas also have secondary couples.

About a cat who is trying to repay favor for being saved by a human. Both of them met when they were a child/kitten, and reunited in their adult years.

I feel the vibe is very similar. The pace of both is similar as well. The whole idea of a group of people in a neighbourhood coming together. Both dramas start from a low point in the protagonist's life and set things right. The entry of the female lead is the turning point in both.

Old Person go to High School both got same vibe and Both dramas have a secret identity. If you love Angry mom then you will love My Boss, My Hero Japanese Drama.

They both have undercover police as the ML with action and romance. A Journey to Meet Love deals with finding more about the FL's parents, and Never Say Goodbye is about illegal drug trading.

Both shows give off a similar vibe. They both portray the hardships of the workplace, as well as the strong bonds that come with it.

Both dramas have a case that is connected to characters that share a tragic past. In both dramas the focus lays on the detectives who investigate the case and the people who are suspects. Both give of a similar vibe regarding the emotional aspect of the cases and the tragic background story.
Both dramas question the topic of "is the law-system always right?"

A story that opens its doors to the Chinese dubbing industry for the first time and follows a rookie and her toxic boss.

sounds pretty much the same as this drama right?

Both main characters of these dramas :
- had traumatic childhood with abusive fathers
- were outcasts
- have similar personality
- had to go against the law to protect themselves
- want to protect those they care about.

Both drama have:
Tragedy, palace intrigues, very angsty and complicated romances, betrayal, loss yet at point they are some very lighthearted moments. Also heavy on the multiple love storylines.

Actually, they are the same. The same plot and the same atmos.
Storytelling and emotions are kind of different and it is due to cultural differences.

In both dramas a woman died in a building. The other tenants of that building are connected to the victim. Throughout both dramas one is left wondering who is the killer and what has happened. Topics such as class-differences, unfaithfulness, lies and manipulation are in both dramas a topic.

Story little different than lie after lie ..
But same thing is mother's feeling for her child,
Fight for her child.

Similar critique & representation of the Japanese criminal legal system, and how it has caused gross injustice to many who didn't actually do the crime but were charged for it.

Both are very slow and refreshing, with a similar vibe, if you liked one, you have high chances of liking the other :)
Both are cute, but perfect and casual has a age gap and First romance is between two students
