Both Search and The Flu are science fiction and thrilling stories about viruses that are infecting people in Korea.

Both dramas doesn't have anything in common... It just comes to my mind because they're both about SOLDIERS.
Search is about virus that's infecting people and Descendants of the Sun is romance between doctor and soldier.

Both dramas revolve around modern, independent, working female leads and issues they are facing in their love/family lives. Both are stories about married couples.

Both Search: WWW and Birthcare Center are comedies and female centered dramas from TvN. Both have different story but I believe that you'll love Search: WWW if you liked Birtcare Center.

Birthcare Centre is comedy drama about career female lead and she's trying to have a baby.
SKY Castle doesn't have much in common. It's more focused on education than mothers/parents and their childs. But it's also female centred plot.

Those two dramas have the same concept of time crossed or merged world. In both dramas are main leads trying to save someones life.

Both Long Vacation and Second Love are Older woman-Younger man Japanese dramas. Both has romance and realistic story.

Both Birthcare Centre and Oh My Baby are comedies from tvN about career female leads that are trying to have a baby.

Both leads are desperately trying to save their loved ones. Also, both are filled with suspense and mystery.

Both (drama and movie) are about con artists but story and background of these two are different. But I still recommend you to watch Private Lives if you liked Parasite.

Although both dramas are really different they have few similarities - female fashion designers, bussines and rich male lead. Our Glamorous Time is fluffy romantic chinese drama and Eccentric! Chef Moon is comedy with pinch of romance.

Both chinese dramas have romance, female fashion designers, bussines and rich male lead who chases/loves them. Plus these two dramas have similar name (at least it sounds similar to me).
