Looking for a webtoon/manhua/manhwa were the MC after she dies is reincarnated as a character from a novel (shocker 😛 😛).

The original character is suposed to work with the queen to get married to one of the prices and make him not get the crown. She works with her behind the scens, but as the prince gets more popular by winning a war he also finds out about the sceem and executes the MC's character.
As the MC don't want to die (another shocker 😛 😛) she decides to tell the prince all about the plans, but still "work" under the queen to not rise suspisions.

Extra info about the characters.
• The MC's character is not the real MC of the novel. It belongs to a lady that acctually don't want to get married but have her own store (I think).
• The prince is not the qeens own son, but the son of the first queen.
• When the prince was young he used to sneak out to fight together with some mercenaries, without telling them who he really is.
• The prince and our MC met when they were young.
• The prince, his younger brother and our MC actually gets along really well, dispite the queen's sceems.

I think that all the info a wrote is from the same story, it's kinda easy to get them mixed up with other stories when they are kinda similar. 😛

Please help me to find the name. 😢 😢

I think its: I was just an ordinary lady?
