Flower of Evil (2020)

Main character also uses someone else identity due to complicated family issues.
She then falls in love and starts a relationship while hiding her true identity.
Mask is more about the lies and betrayal between the couple, their relationship is more complicated and not as stable as in Flower of Evil.

die serie ist änlich . er gibt vor jemand zu sein was er nicht ist und spielt gut . bisschen zeitreise is dabei das hat mich gestört aber sonst recht cool

SIMILARITIES
• Both follow a married couple with a child (both are daughters)
• Both couples both struggle with their relationship at one point
• Someone in the family is kidnapped (/held hostage) at some point
• The stakes are pretty high in both dramas - you will feel tense watching both dramas
• Both are mystery and thriller - crimes that take place in present time are related to characters' past, so there's multiple mysteries to an extent

DIFFERENCES
• Flower of Evil follows a morally grey character ML who has been through a lot but still wants to do everything he can to protect his family. Whereas in My Family, the ML is basically an absent father who doesn't pay attention to his wife or daughter.

Both have the same general plot and similar scenes, with the M L hiding his past from the FL who is his wife and in law enforcement, as all the while she begins to suspect him of being a murderer. SOY shifts the setting to ancient China, while FOE is modern day South Korea.

Both shows make me experience similar suspense, angst and thrilling moments. Both are fast-paced in terms of dropping clues and relations among different characters, building a great momentum in each episode to keep me curious on what's next.

Although Baek Hee Sung is hiding a dark secret surrounding his true identity, he has established a happy family life and a successful career. He is a loving husband and doting father to his young daughter. But his perfect façade begins to crumble when his wife, Cha Ji Won, a homicide detective, begins investigating a string of serial murders from 15 years ago. Ji Won notices changes in Hee Sung’s behavior and begins to wonder if he could possibly be hiding something from her.

Same screenwriter. If you like the family fluff/drama part in Flower of Evil, I think you'll like I Introduce My Father too.

Completely different genres as one is based on a crime, one is sci-fi but..
Both romance
Both explores acceptance, embracement and loneliness.
FOE - male is lonely and female comforts
MHL - both lonely and comfort each other
Both have traumas.
Both have a nice and cold guy within one person/face
FOE - male's facade (who he wants to show)
MHL - man and robot (who he wants to be)

They are both horror/mystery/crime stories and have a similar dark vibe. They both deal with serial killings, even in the Children of Nobody take place in the present. But in both cases the answer is in the heroes'/heroines' past.

Same ML type as in Alice. Both have lack of feeling
or understanding emotions disorder. They don't process emotion
like average people can. Both have a Police officer as Main Lead.

The similarity between these two series is vague but still there. My pov is focused more on the main characters and the relationship that these couple hold.

Both these series have the main couple in love, fighting for themselves and protecting each other from the worst.

The female leads are strong and kick ass. Both have detectives and female leads fighting to protect their loved one.

If you love to see a sweet bond between the main couple with action....this might be for you!
