Both about a woman who lie about her age and pretend to be younger to be hired in the wanted workplace.
Dramas with older women/younger man and hidden identity of female leads as main plots.

At first one may think that the common ground with these family dramas are just that their stories are child-centered with Shin and Akiko doing the best for Kotaro and Miyuki respectively. If you like Akiko's personality, you probably would like also Kotaro's and vice versa. Both have comedy elements and gives off that warm feeling you often get with good jdramas.

In 3 Will be Free, Tay Tawan plays the son of a mafia boss, much like Gun in Golden Blood. Gun and Tay share a lot of characteristics, they both want OUT of the mafia business and want to just live their lives. Both get targeted by OTHER mafia bosses. In 3 Will Be Free and Golden Blood, both have a second Male lead who is the protective type (Joss in 3 Will be Free and Boat in Golden blood). Both have LGBTQ+ characters. 3 Will Be Free is definitely the Rated R version of Golden Blood.

Same technique

Helping people by solving their problems
Only difference is their work occupation (MPUB is Bar whereas SL is laundry)

Can i just say it?
The plot of this drama itself tells us this is exactly similar in a different way.
Canola in return just tells us about how a girl so different and a grandma who is supposed to be dead, living together. While this drama shows us the same vibe in a different way

They both have a mature theme although it's okay that's love focuses on the psychological aspect I still find some similarities

Both stories share a ML that does shady things for a living, but are sweet hearted at the same time that they would do anything to protect their loved ones even start a rebellion (like in rebel: thief who stole the people).

Also in both the king has a unstable state of mind, gets manipulated by a woman and had daddy issues...

The vive in both is really positive, the protagonists are always plotting something but for the grater good and against of the evil power.

Even one of the main songs that come from the Joseon era folklore is present in both, in one sung by a woman and in the other by a man.

A relationship that started in lockdown. Both have a lead that has a secret crush on the other lead. This lead which has a secret crush has the support of his friend/s.

them both are pretty similar.
the story told about old-vibes high school student with fluffy romance, strunggling for their youth age and someone they loved.
Both are presented in the form of a film

Both films show a LGBTQ+ relationship where one man might harbour feelings but is cold towards another who is deeply in love with him.

Both films depict a complicated LGBTQ+ relationship where one man is a bit elusive with his real desires while another man is madly in love with him/trying to win him over.
