Adapted from the manga series "Anata Wa Watashi Ni Otosaretai" written by Miyaguchi Jun and illustrated by Umesuzu (??).

Both drama are about a Psychological criminal cases
Both dramas have a detective with close relationship to the suspect
Both dramas have trauma from childhood

Going by the plot of the 2 dramas, they are not similar, but when I was watching Flower of Evil, I kept thinking how similar it is to Confession.. Later I found out that they have the same director and no wonder I felt that way.. Both are crime/suspense/thrillers but Flower of Evil has elements that can make you cry and it has romance as well.. Confession on the other hand does not have a romantic plot.. But both are very interesting to watch

1. The premise is kinda similar: Both Trolley's FL and FoE's ML have secret pasts. They're afraid if their significant other learned their pasts, it would affect their married life.
2. Both Trolley's ML and FoE's FL tries to protect their significant others in some way.

Just the feeling is where the secret is being held within a family. Though not the same story, that intrigued sensation all along is priceless. Also, teaches valuable morals. I loved them both mystery scary thriller genre.

A psychological drama about unhealthy interpersonal relationships explained often through elaborate flashbacks. Takanako Mayuko, who grew up in an idyllic mansion with the perfect loving family, blames her childhood best friend for everything that has gone wrong in her life. While maintaining the façade of friendship, Mayuko finalizes the revenge she’s been secretly plotting for decades.

well, so many people have given out recommendations and i am surprised that no one is yet to recommend Voice season 2 and 3 when the male lead character there is so similar to the one in Flower of Evil. in fact Voice series are OCN dramas so they are meant to be a lot darker and with less emphasis on romance which could be a plus for a genre like this. there is a good reason why the Voice series keep getting season's extension, you gotta watch it to know. enjoy!

Both male leads hide their dark sides behind a friendly facade. As the drama progresses that mask starts to slip.

Hear me out! the dads! + acting in both dramas is superb, the dialogue and how the screenwriter used timelines and flashbacks

Similar feel.

Both dramas are dark thriller/mysteries in which the main characters are a couple and their young daughter and (one of) the SML(s) is a newspaper reporter. Both dramas have a lot of misdirection/red-herring which keep you guessing what's happening/who the villain is, and both have common plot elements of a killer in a raincoat, a car accident, and amnesia.

Both dramas feature the characters lives being torn apart through a traumatic past and multiple killings. The main focus of both this dramas is on two characters, one a detective, and the other who is a psychopath. In both of these dramas, the psychopath and detective have a familial relationship.

- ML has antisocial disorder (does not understand human emotions);
- ML watches others and mimics human emotions;
- smart and antigonist-type ML;
- FL changed ML's world

- seemingly perfect couple but one has secrets to hide
- ml is the problemed person in both the series

Flower of the Evil and Blood and Ties are both very dark and brutal dramas. Both deal about families where one member has a secret past tied to a crime and another member finding out about it. In both dramas this crime revolves around a murder.
In Blood and Ties it is however the daughter that is suspicious of her kind father, whereas in Flower of the Evil it is the wife that doubts her husband more and more.
Both dramas feel very similar.
