Hello, Goodbye, Momma! Goodbye, Kim Tae-hee (Cho Sung-hoon), who was dead five years ago, reappeared in front of her dead husband just after five years. To be a whole person again, she performs a reincarnation experiment for 49 days. The result? A son who is as smart as his parents and more spirited than a cat!
Two high school girls, Kim Tae-hee’s daughter Min-ja and her niece Chul-soo, are the subject of this story. When Min-ja gets lost during a trip to Korea, Kim Tae-hee adopts her as her own daughter. She teaches the girl all that she needs to know about being an eternal monarch and how to rule the world. Things do not go well, however, because Chul-soo falls in love with Min-ja even before she is officially adopted. The two become close friends and she becomes very upset when Kim Tae-hee learns that she cannot have her own children due to their heritage.
One evening, Kim Tae-hee goes to fetch her baguino at the supermarket when she runs into Oh Yea, a street vendor. Oh tries to sell her the baguino, but she ignores him. He then decides to give her some flowers, telling her it is the least they can do for her. On the way home, he tells her he likes her and she feels sorry for throwing the baguino on the pavement. Kim Tae-hee throws back the baguino, angry at Oh who just laughed at her without even trying.
This movie is very funny because it is about so many things. Kim Tae-hee plays the role of a typical Korean girl who knows how to play the system and skirt around tables to get what she wants. Oh tries to be sincere about wanting her to be honest, but she still cannot win her case. Kim Tae-hee eventually gets the girl she wants by winning the grand prize in the Squid Game, which is based off an English cartoon. The two of them are then taken to the Los Angeles Film Festival where they meet their co-stars Gong Yoo and Jang Doo.
The next day, the women sees their mutual friends Oh Yea and Kim Tae-hee in the hospital and Oh decides she wants to give up acting and enter the medical field. She tells Kim Tae-hee that if she accepts the acting award in the film festival, she will automatically become their company’s number one super star. The two women have a heart to heart talk and after Kim Tae-hee realizes that she wants to enter the medical field, Oh Tae-hee tells her that they should try and become the number one singer and actress in the country. That would make them a kpop princess and make them more popular than the average girl, which would make them the kpop megastars.
In the meantime, Kim Tae-hee gets her chance to act again when she appears at the hospital to pick up Joo-yong. After the doctor tells her that she can no longer sing or act, she goes to the korean drama competitions where she sees Park Ye-ra and Choo In-joo. They compliment her acting and ask her if she will be their acting teacher this time. She accepts the offer. The drama club becomes her career path.
After the incident, Oh Tae-hee gets herself a role in another K-pop movie and after that she was discovered as one of the best actresses in the country. In the end, her net worth swells to an estimated $40 million. The net worth of the various successful actresses in the country has risen steadily since the turn of the century and is now rivaled only by actresses in Hollywood. With a star like Kim Tae-hee at the helm, the korean film industry could not get any better.
While all of this was happening, Kim Tae-hee was developing her acting skills and her net worth increased along with it. When the film industry went into trouble, Kim Tae-hee got out of the industry. She then entered the world of internet marketing and joined Netflix, one of the most successful online streaming services today. She became its first celebrity representative and started to develop her own brand there.
