Yes. My Demon originated from a manhwa and has made certain changes to fit the medium of the adaptation. But the core elements and storylines are drawn from the manhwa source.
One of the common themes is war strategy. In 'kingdom of war fanfic', there are often detailed descriptions of military campaigns, from planning attacks to defending strongholds. Another theme is the role of magic. Magic can be a powerful weapon in the kingdom's wars, and it often has its own rules and limitations. Also, the theme of sacrifice is prevalent. Characters may sacrifice themselves or their own interests for the greater good of the kingdom.
In "Evil Emperor's Domineering Pet: Defiantly Domineering Concubine", Ye You was the guard of Taijie of the Blue Moon Kingdom. I recommend a similar ancient romance novel,"This Queen Is Such a Woman." The story will take you into a fight in the palace. The female protagonist, as an abandoned concubine, wants to return to the front. She is not strong enough, but she is smart, brave, and never admits defeat. She will use various methods, including using the rogue prince in front of her to continuously gain strength and return to the land of love. I hope you like my recommendation. Muah ~
Well, you could try doing things he likes together to strengthen the bond. Also, showing appreciation and support for him can go a long way. Sometimes, small gestures of love and care can make a big difference.
One way could be to have heart-to-heart conversations regularly, listen to his perspective, and work on resolving any conflicts together. Surprising him with small gestures of love and support might also make a difference.
