Both dramas are workplace romance genre. Main focus of the story is the love line, but also explores the daily lives and coworkers relationship.
FL are kinda similar, both of them had to start working early in life and are trying to improve for a higher positions in their current job.

Similar vibes so far. We can expect a melodrama genre from Curtain Call as we also had in Mask.
A person goes into a rich family household to act as someone else.

Park Seo Joon is one of the lead roles in both dramas; the male lead is a chaebol, the female lead a hardworking person... something traumatic happened in their past as kids, but it was burried by their family and memories.
Both have humor but also dramatic background.

Both dramas are historical gender, but Queen for seven days is more dramatic. I think they are similar because Shin Chae Kyung in Queen for seven days is the child of one of the king's subjects, so as Gyun Woo in My Sassy Girl. They both have relationships with princess/ princes.

Romance between a prince/ princess and a subject. Both dramas have humor and romance. Love in the moonlight the girl is poor, but in My Sassy Girl the boy is from an important family. Similar feels.

Both dramas have law and politics as main plot. Defendant is more drama because the case itself involved the prosecutor life; in Stranger, the prosecutor's family is not involved on the case, his life is not the main plot.
Both have a reliable and strong female lead. In Defendant is the lawyer and in Stranger is the Lieutenant.

Both are medical drama, same kind of vibe where the main leads have family situations related to hospitals. In both dramas, one of the main leads have to leave a position in a big hospital in Seoul and move to a small one, with less technology and resources: in Teacher Kim, a countyside hospital and in this drama is a hospital ship.

Both dramas are about a CEO of a company who has difficulties of talking in public because they have different personalities. The girls are more extroverted and they get involved because of workplace.

Both dramas have a plot of a girl who sees ghosts and is scary of them. The girl gets involved with the male lead because of ghosts.

I don't think the plot has a lot of similarities, just I had the same vibe from the 2 dramas. Both give a warm feeling.

Warm and Cozy reminded me of Personal Taste because the leads have a situation of living together and they take care of each other.
I think they have a similar aura of becoming friends before, and then, romance.

Both dramas have a restaurant background.
The male leads are chefs and own restaurants.
The male lead help female lead with finalcial problems.
