The CDrama is a historical fantasy, while the KDama is a modern fantasy based in a high school. In the KDrama FML behaves like the main character, who is rich, and has a cold fiance/bf who doesn't like her. She has a heart condition so she faints a lot and can die any time. One day FML finds out that she is a book character, but not the main character, she's one of the support roles, who's used to connect the real ML and FML. Her fiance/bf isn't the ML in it either. Days go on, and she has to follow the set script until one day she notices someone who is not even a support but a background character who doesn't talk or interact with anyone. She takes an interest in him... And the real story starts.
From the trailer of the CDrama, they seem pretty similar in terms of concept. But what is unique is the setting and how will the characters be portrayed.

It's the same thing, except one is about physical strength and the other about cooking. In both shows 100 contestants compete to become the best in Korea.

Has a similar contract marriage. both FML have a troubling past but it's different. Has 2nd and third couples.

Both FMLs mother and father do not treat their daughter's rights.

In NGNL, FML parents always take in children, in foster care. This results in not taking care of their own daughter and if you ask me it's pretty obvious that the daughter hates that her parents dont care about her because they are constantly spending time, with the foster kids. And it's not a one-time thing either, but a constant one, when one foster child leaves another one is brought in. This makes her dislike the kids as well because they are taking her parents away. Although I understand that fostering and giving a roof over the heads of children is good, not paying attention to your child makes it no good. No point tbh. Even if the parents have a lot of love in their hearts for their child, there is no point because on the outside the lowkey abandoned her. Its basically giving -- you live under my roof, I cook, clean, and give you clothes and money so I'm doing everything a parent should SO ME NOT mentally taking care of you, not watching you, not talking to you, not asking about school, not nagging out you should not be a problem.

Similarly in LLTG, the parents of FML abandon their child at 3 years to fight war. They took all her other siblings with them but left her behind with her calculating grandma and aunt. For the next 15 years, her parents are in the war, neglecting her and her grandma and aunt treat her like a rat. They dont give her good food, clothes, or a place to stay, BTW her dad is the provider for the whole family so technically they should treat her like a princess to stay in good with her dad. But they dont obviously. They even sent her to some old house in the suburbs, where she has one maid, more like a sister and a nanny/house help. This nanny takes all the money does not give 2 shits about FML, and gives her bad food, clothing, etc. One day the war ends so her parents send a letter that they are coming back. The grandma sends for her to come back. She ends up coming in at the same time as her parents. The grandma lies about FML being bad and to teach her a lesson they send her to the countryside. Although FML tries to refute her parents dont take her seriously. Now that her parents are back you'd think they'd shower her with love but they dont especially the mother. She treats he daughter like a soldier that's gone stray, has no discipline, and instead gives more love to the calculating aunt's daughter. They dont understand that she's been on her for 15 years but treat her all garbage.

as soon as I read the jdrama synopsis it reminded me of extracurricular except the roles are flipped.

In the Kdrama the ML is poor and takes advantage of classmates to earn money (there is a lot of context behind this). I believe he doesn't have a mother and his father is up to no good either. And the FML is rich, she has everything she could think of apart from freedom. One day she finds out what the ML is up to and takes part in it for fun and to run away from her family.

According to the jdrama synopsis, the FML is poor and has a single mother. To earn money she takes advantage of classmates situation. ML on the other hand is rich but has no freedom. One day ML finds out about what FML is doing and takes part to make money and run away.

It's a similar trip setting with friends, eating food, exploring places, and doing new things! Bon Voyage has all the BTS members whereas Are You Sure includes Jungkook and Jimin.
