Manual for Raising a Crown Prince

It was rumored that the prince in the capital was a dandy and arrogant, and she saw it as soon as she returned to the capital. Unexpectedly, the emperor granted them marriage and tied them together. It's okay, he was ignorant and incompetent, so she educated him personally; he was illiterate, so she found someone to teach him; he was powerless, so she turned him into a martial arts wizard. But the country was in trouble, so he went to the North Country on the condition of being a hostage. She ignored the heartless words he said and stayed alone just to save him from the fire and water. "It's just the North Country, I want to paralyze its economy." "It's just the North Country, I want it to never invade our territory." Ps: It's definitely a sweet article, and the companionship flow couldn't be sweeter. Strong women and strong men, but the male protagonist grows up slowly!
