Need recommendations for some heartwarming novels

Hey everyone! I’m looking for novel recommendations that focus on adventure, excitement, and meaningful relationships built along the journey. I’d love stories that feel heartwarming overall.

Ideally, the protagonist is likable, thoughtful, and kind to others—but still capable and not naive. I’m fine with the story having some serious or darker moments here and there, but not being overwhelmingly grim all the time.

I’d also prefer books that have little or no explicit content. I’m more interested in stories that show relationships developing naturally over time. Some wholesome or “vanilla” moments are totally fine—just nothing overly graphic.

Recommendations from any format are welcome: traditional novels, webnovels, or Japanese, Korean, or Chinese light novels. I’m just in the mood for a good adventure with strong character relationships!
