the is one suitor, her childhood sweetheart, although she didn't really ever consider him as she doesn't care about romance. No love triangle here

FL wanted a child, she planned it and she got one. She made sure he was her priority and knew that in an "everyone for themselves" chaotic warring era, she was the only one who could be trusted to take care of her son. She kept him really close. She took care of him, protected him, educated him, considered him in everything and disciplined him when needed. Plently mother-child fluff

1. She's modern but she's not obvious about it, more in her confidence and mindset. No preaching or superiority complex here. 2. She adopted a child with a very special identity but he actually never made a glorious comeback to raise her status or face-slap her enemies, he was just happier living as her son than fighting for his "birthright". 3. Villains weren't really important or long-lasting enough to be a problem, no real antagonist here. Some annoying people and small foes but FL never bothered wasting time with them, too busy developing villages, raising children and making money. 4. At the end, she's technically the princess of a small territory but it's just a convenience thing and she just keeps living her life as usual. 5. No saving the country or building an empire that will last ages. From historic knowledge, she recognized it was most likely a chaotic era that involved constant warring and change of dynasties during 50 years, so she only ensured to develop a smaller independent territory and try to keep it stable without really getting into the fight for the throne
