Kamisama no Uroko
In which our mc is sold of as the bride to a dragon after his descendants make a promise with this dragon. Cute things and fluff ensue!
Hualongji
In which our mc was originally a carp but was turned into a dragon for doing whatever the fuck he did (he climbed up a waterfall or something). After that, he got a human form and protected his people of the sea. For killing these people who were terrorizing his people, and so he got captured by this dude.
Where the Dragon's Rain Falls

Haken No Kouki Altina (novel)
In which mc, a failed soldier, did something wrong and so, is forced to go to the frontlines. One day, he is transporting a civilian somewhere, and they get attacked. Although weak, he attempts to protect her, but finds out that the "civilian" is actually a princess known for fighting with a large sword. When the attackers are defeated, the princess offers mc the position of strategist/tactician for the army. At first, I thought it was hella slow. However, it gets better and better. A total must read. (I also have a guilty pleasure of strong girls and weak, but smart, boys. Ehehehehe...)
Lady Baby
In which our mc is a noble and all her family members die within a war for various reasons. One day, a supernatural being comes down and hears her singing. Entranced by it, the being gives her another chance to live, starting as a baby.
