Gumiho: Tale of the Fox's Child (2010)

They ressemble each other in the Gumiho thing.

Both involve the tale of the Gumiho's child however Gumiho: Tale of the Fox's Child focuses more on the childhood in comparison to Gu Family Book

If you enjoyed the lore of the gumiho you might enjoy Gu Family Book. Both shows take aspects of gumiho lore. They are both based in historical era's. They both also have the aspect of secret keeping.

Well their are both about Gumiho, I think that were the similarity stop , the second one is a little more deep, and has more emphasis on human betrayal and that.

Need more shows where Kim Yoo Jung shows her versatility as a child actress? Grudge the Revolt of Gumiho is for you
There are a lot of elements similar to the stories:
-> Both are sageuk, but both dramas contain fantastical elements (shamans, curses, prophecies)
-> the sweet and talented beautiful young girl believably played by Kim Yoo Jung
-> basically, both Kim Yoo Jung characters entered a place (palace in Moon Embracing the Sun, Yoon’s house and surrounding town in Grudge the Revolt of Gumiho) and her charm and beauty impresses some powerful adults (king in moon sun, head of Yoon household in gumiho) making rival girls jealous
-> there is a sweet childhood love story in both dramas, except in Gumiho, the childhood love story is not the main plot.
-> The guy playing Kim Yoo Jung’s lover in Gumiho is Lee Tae Ri/Lee Min Ho 93 (aka the young version of Yang Myung in Moon Sun)
-> The above basically means that if Yeo Jin Goo (young Hwon) and Kim So Hyun (young Queen Bokyung) have Missing You, then Yoo Jung (young Yeon Woo) and Lee Tae Ri (young Yang Myung) have this drama Gumiho fox child
-> Find the scene where Kim Yoo Jung/Han Ga In are following butterflies?—> there are at least two cute scenes in Gumiho where Kim Yoo Jung and her lover are enjoying fireflies. Both dramas actually have two young couples meet because Kim Yoo Jung’s characters were following insects
-> The main villain family in both dramas both have the last name Yoon. Both fathers wanted to kill Kim Yoo Jung’s characters for their benefit and both daughters are evil, ruthless, and are jealous of Kim Yoo Jung’s characters (especially because the guys they like like Kim Yoo Jung’s characters)
-> SOME SPOILERS: Kim Yoo Jung’s characters both “died” in these dramas, and her lovers in the respective dramas were too helpless to save her. Both dramas also make people feel for the grief of a family/lover, for the death of an innocent young girl.
-> SOME SPOILERS: In both dramas, after the “death” of Kim Yoo Jung’s characters, both characters appear on the lives of other people they had affected when they were young, appearing either as a dream to the people she loved or somehow haunting those that hate her (particularly the evil Yoon girls)
-> Shamans have great involvement to the events in both stories
-> Other actors that appear in both dramas aside from Kim Yoo Jung and Lee Tae Ri/Lee Min Ho 93 are Yoon He Seok (Sungkyunkwan student who became a guard or warrior in Moon Sun/ Kim Yoo Jung’s lover’s dad in Gumiho) and Jung Eun Pyo (Eunuch in Moon Sun, Kim Yoo Jung’s biological dad in Gumiho)
Gumiho does not focus on romance unlike Moon Sun, but it has many elements similar to Moon Sun and has some romances between its complicated characters. This Gumiho show was in 2010, and I firmly believe that it was her experience in this show that helped Kim Yoo Jung prepare for her role in Moon Embracing the Sun

=> Both are historical dramas where a mother is the main character
=> They may not have many similarities but both shows have a similar theme: to what extent parents can do for their children. Both dramas depict the good and evil in parents.

- Both begin in Joseon Period
- Both include leads who are nine-tailed foxes ( admittedly the relationship whilst including a romance is more focused upon mother and child)
- Both include supernatural abilities and themes
- Both include interspecies relationships(between the supernatural and humans)

Tale of the Nine Tailed fans, if you are enjoying Lee Tae Ri as Imoogi, please let me inform you that it is not the first gumiho drama that he has acted in. 10 years ago, he acted in a drama called Gumiho Tale of the Fox's Child/Grudge the Revolt of Gumiho. He's only a supporting character here but his character is also quite important since he is the love interest of the gumiho child (played by Kim Yoo Jung). Notice also that he and Kim Yoo Jung also acted in Moon Embracing the Sun as child actors (although his love for her in Moon Sun is one sided).

I know the dramas are kinda random, but if you came to see Iljimae to see Kim Yoo Jung in her child actress days, then I definitely recommend you at least see her scenes in Grudge the Revolt of Gumiho. It's her first lead role in TV. If you see her romancing Yeo Jin Goo (her lover in Moon Embracing the Sun) in Iljimae, definitely check out Gumiho Fox Child for her romance with Lee Tae Ri (formely known as Lee Min Ho born 1993, he's another lover of Kim Yoo Jung in Moon Embracing the Sun).
In both dramas though, Kim Yoo Jung plays a good kind hearted girl. There are also a few scenes in both dramas that are quite similar. In Iljimae, Kim Yoo Jung enjoys the company of a bird while in Gumiho Fox Child Kim Yoo Jung enjoys following mostly fireflies and sometimes butterflies. Another scene is where Kim Yoo Jung is helping one of the young male characters heal their wounds. And another one is where Kim Yoo Jung's adult version Han Hyo Joo is enjoying the lanterns while being watched by one of her love interests in Iljimae is similar to Kim Yoo Jung in Gumiho Fox Child where she was also watching the lanterns while her male love interest looks at her so lovingly.
