Julie3604's Things

This is such a shot in the dark but does anyone know of this historical (possibly isekai) manhwa where the FL goes around and investigates something and she goes to a company and buys info from them. There were several love interests and they used a trading company (?) as a front to sell information for people with the right price. There was also this whole ordeal with the FL and her older brother and how he didn’t want to be part of the fight with succession so he went away to become a priest/mage. They had this whole reunion together after the FL found his whereabouts with the help of the other love interests. I remember the FL would always go out of the royal castle to sort out her hidden fundings and affairs within the town. Starting to believe this was a whole fever dream I had ╥﹏╥
