Hello!
I read a manhwa a while ago that I would like to reread, but I unfortunately cannot find it. This is what I remember from it: there are two siblings competing for the throne. They have distinct hair with the FL having purple and blue hair and her brother having yellow and red hair. While they are competing, they still care for each other. The ML was a friend of the brother's who fell in love with the FL. The ML is the head of a people without land, and is helping the brother to get land for his people. The FL gets the throne because the brother gives up. He initially had a political marriage and fell in love with his wife. They had a son who did not have the royal families characteristics and he didn't want to put his son through being royalty. There is a world tree and the ML has powers to unlock it I believe. The FL gets dreams of her past life where alternative events occur.
I would appreciate any help in finding it!
Are there any recommendations for stories like Guiding Hazard? I'm mainly looking for stories with strong characters, an interesting dynamic between the characters, and consent.
