same director

Police drama with focus on cases with retro themes. They even use sense of smell and retro font styles. The drama takes place in a building with old school style. The focus is om people and not technology

Revenge theme by a twin sister who is not who she claims to be ; sizzling chemistry with a ML who saves her repeatedly ; fight for control of a company ; hidden evidence record. Plot holes bridged over by the chemistry. Repetitive but nice music.

Both have very similar male and female leads in personalities and capabilities. Both male leads give off the impression of being weak, but are very intelligent and have built up their resources/intelligence network over time. Female leads are cunning and lovable. There is both a political and family plot, and most importantly, the dynamics between the leads, trust, and teamwork are exceptional with little to no miscommunication.

1. Both have two strong-headed female leads.
2. The male leads are a bit unhinged but have a good heart.
3. The two main characters have great chemistry, with hints of romance, but the story never fully explores that genre (which is frustrating because the pairings beg for romance).
4. A major case connects both of the leads' childhoods.
5. The plot revolves around the discovery and mystery of the ongoing killings.
6. Unlike "May It Please the Court", "Memorist" doesn't focus heavily on the legal aspects, but rather on unraveling the mystery itself.
7. The identity of the killer remains unknown until the very end.
8. The series is intriguing and keeps you hooked throughout.

revenge story in both cases but RftA has a FL that managed to be a likable one whereas in The Lady Commander I understood the anger of the FL, but could not find her methods kosher

Both MLs have feline characteristics and a group of close friends/allies who all work together. Both have minimal romance with a focus on friendship and bromance.

Both have animal-human characters, good fight scenes, and the ML's journey. Both have a similar feel.

Both FLs have low self esteem and find a way to transform themselves into someone different and popular. Both MLs know their secrets and love them for who they truly are.

Let Free the Curse of Taekwondo just started so I can't really tell if it's gonna be that similar but the two first episodes reminded me so much of The Time of Fever
-Daddy issues (father hits son)
-The son wants to run away fron the father violence
-Puppy like main character
- Tough main character that wants to protect puppy like main character.
