Both main leads start living together (in the same building, but different floors) and due to their communication solve all of their problems.
Both dramas have good communication between the mains (mainly, but not only throught conversations).

Across the hall neighbours (a man and a woman) whose terraces looks towards one another start to interact both at their daily and work life. Soon they start to fall in love. Both are very slow romances.

Male protagonists manages a company about clothes and design.. female protagonist is a designer. Both man suffer through hardships, because of females, obsessed in them since childhood.

The male protagonists' fashion company struggles to obtain a sertain clothing technic .. while the female protagonist is a designer and a student of the person who has the rights over this technic. Many episodes revolve around the obtaining of the rights for it.. others are about family intrigues and such inside the company and it's rivals. The main protagonist in both struggles due to the unhealthy obsession of two other women whom he somewhat takes as his sisters.

Both female protagonists are fashion designers.. male protagonists are CEO's of companies involved in fashion..; male leads have annoying female childhood friends, which grew up with the agenda of marrying them.

Both are about the professional life and struggles of modern script-writters.

Both have a girl, which talks to a ghost, who was once in love with her and revolve around making peace with him.

Both have characters which closest people aren't actually alive and present. They involve that person's sad story from the begining to the end of the show and talk about receiving the right amount of psychological help and love + support from your friends and family.

Somewhat slice-of-life dramas which involve:
- young gay man and his love life struggles + the young woman which is closest to him;
- the friendship of 3 + 1 girls (which knew each other since school or colleague..);
- 3 girls and a guy living in one house to help the female protagonist's emotional and financial problems (and their own life);
- a friendship between 3 men;

It involves a few female friends and their life and career desicions. Looks throught the girls different personages and the different way they tend to resolve their problems.

Both have a male protagonist who is a pianist (and was a child prodigy). The female protagonist is also a musician, but lacks the talent the male protagonist have.

In both a cutesy female celebrity dates a person with very serious profession, who is a professional at his work, but doesn't know how to communicate well.

In both dramas the female protagonist rarely withdraws from picking a fight about the injustices she encounters in the office. The guy is the timid one and often is viewed as someone or too angelic or as someone who is just too weird.
