Its story might be what makes it unique. It could have a particular plotline that delves deeper into the emotions and relationships of the characters in a way that other BL graphic novels don't. For example, it might explore certain aspects of the characters' personalities more thoroughly or have a more complex relationship dynamic. Also, the cultural references or the setting it uses could be different from the common ones in the genre, which adds to its uniqueness.
Well, 'A Guy Like U' is all about the evolving connection between the main characters. It has beautiful art and compelling character development. The plot is full of surprises and emotional moments that make it really engaging.
Well, from what I've heard, 'Are you here to kill' manhwa might have a dark and thrilling plot with unexpected twists and turns. But that's all I know for now.
One similar work could be 'Given'. It also has elements of BL (Boys' Love) and is presented in a graphic novel - like style with great art and an engaging story about the relationship between the characters.
