One of the best highschool novels is 'The Perks of Being a Wallflower'. It beautifully captures the coming - of - age experiences, including friendship, first love, and dealing with mental health issues in a high school setting.
It has ended. The last chapters wrapped up the plot and brought the manhwa to a close. There might be spin-offs or related works in the future, but the main storyline is completed.
The Highschool DxD manga has indeed finished. It wrapped up after completing all the planned story arcs and providing a satisfying conclusion for the readers.
