Hi Bye, Mama is one of those dramas that makes you dive right into her story.
It's about a woman who died in a car accident. She was pregnant and the baby was saved by the doctors.
She lives as a ghost on earth and watches her loved ones. She lives with other ghosts with whom she has made friends in an urn hall.
5 years after her accident, her husband remarried, her daughter thinks her stepmother is her biological mother and her parents have broken off all contact with the child. However, she knows that they all long for closeness. Due to a circumstance, Cha Yu-ri (FL) gets 49 days to take her place on earth. This means that she will become a full human being again when she marries her husband again and her child recognizes her as a mother.

That all being said we have a storyline which could have been surrounding the ghosts she lives with, the drama around her family (especially her mother), her husbands new wife, her husband and daughter and her friends, which are all there for her and missed her.
This was pretty much done in the first 7 episodes, maybe?

After a while, however, I was bothered by more things than I liked. For one, there was constant repetition of scenes (which is not unusual in dramas, but it was true very often), but that wasn't enough, because the same dialogues were also always repeated "I'm sorry", "I'm so glad", "I just love Son-woo so much, she's so pretty" are definitely the top 3 phrases of the series.
The acting was also mixed, but that was partly due to the script and director, since I've seen dramas with the actors and it wasn't that bad there.
Partly I could not understand the characters. Information was constantly hidden and things were not said. Most of the main characters spent most of their time looking stupid or crying. In addition, there was far too little questioning for me. If someone I knew came back from the dead I would really have a lot of questions. Also, there were too many plotholes. Especially concerning the days she has left and also concerning the ghosts. You are introduced to about 10 at the beginning, which have deeper storylines, but which are dropped to make room for repetition. During the series, Yuri promises to do something good for the ghosts, which she does 2 times and then has forgotten the things.

The Stroy had the potential to be funny, varied and dramatic at the same time. This was not used in that many characters and questionable things were simply forgotten. The last episodes just upset me.

Nevertheless, I often had to cry. My favorite character is the stepmother.
