Need help finding a story

I don’t remember if it’s a manga/hua/hwa or if it’s BL but afaik, the story follows a hero who is now in the modern world, he no longer has a purpose after the princess he was supposed to protect gets married with the dragon he was supposed to defeat. Then the lovey dovey stuff happens, he has a dilemma and consults the princess and stuff. I really wanna read it again I can’t get it off my mind lol
