You could look on platforms such as Comico or Lezhin Comics. They often have a decent selection of BL manga. Just be aware that some content might be restricted based on your region.
The emotional depth is a key characteristic. In many good yaoi bl stories, the characters' feelings are not just surface - level. In 'No. 6', Shion and Nezumi's relationship is filled with a mix of emotions like fear, admiration, and love. And the setting can enhance the story. If it's a school setting like in some yaoi bl, it can bring in themes of youth and discovery.
Another characteristic is the use of visual elements. Since they are visual novels, the illustrations play a big role. The scenes are carefully designed to enhance the mood of the story. For example, a romantic moment might be depicted with soft colors and gentle lighting, while a tense or conflict - filled moment could have darker hues and more dramatic shading. This helps to draw the reader deeper into the world of the story and the relationships between the characters.
Sure, Yaoi manga is very real. It typically focuses on romantic and sexual relationships between male characters. These mangas are created and consumed by many people around the world.
I think 'Sasaki and Miyano' is also among the best. The story is set in a school environment. Miyano is a fudanshi (a boy who likes BL) and Sasaki is a popular boy in school. Their relationship starts from Sasaki's interest in Miyano and slowly blossoms into a deeper connection. It has a lot of cute and heart - warming moments, and the way their relationship progresses feels very genuine. It also touches on the insecurities and self - acceptance that the characters go through.
