The intensity of the emotions. In BL novels like this, the love is often expressed in a very raw and passionate way. The characters might be 'idiots' in the sense that they struggle with their feelings at first, which makes the story more relatable.
Well, I am addicted. The beautiful art, diverse plotlines, and the exploration of emotions in BL manga make it hard for me to resist. Also, it offers a unique perspective on relationships that I find fascinating.
Maybe it's the engaging storyline or the well-developed characters that caught your interest. Or perhaps it's the unique art style that appealed to you.
There are several options. Some dedicated manga reading apps like Manga Rock or ComiXology could have what you're looking for. Also, some websites specifically focused on BL content might have a good selection.
