I am looking for a book or the webtoon that was based on that book. I lost my webtoon account and I can't find the title.
As I remember, it was about a boy with superpowers (probably lightning) that was sent to army(?) school to practice. His nemesis was a slick Malfoy-like boy with white hair. It was also tagged as BL, but I didn't make it to that point of the story. A boy was mentored by some general.
I know that the book was published in English and then someone created a webtoon based on it.
