I could be okay with BL sandwiches in manga if they are well-integrated and add something unique to the plot. But otherwise, I'd rather they weren't there.
It could be quite an interesting experience. You'd be part of a unique fictional world. You might witness the main characters' love story unfold from the sidelines. Maybe you'd get to see the omega and alpha characters interact in their special ways, like the possessive glances of the alpha or the shy yet alluring behavior of the omega. And you could be in the background of all those omegaverse - specific events, like the mating ceremonies or the pack gatherings, which are often full of drama and passion.
It would be quite an interesting experience. You'd be part of a unique fictional world. You might witness the main characters' love stories unfold from the sidelines. There would be a lot of new rules and social hierarchies to understand, like the omega - alpha - beta dynamics. And you'd probably get to see some really cool and different settings that are typical of the omegaverse.
The appeal lies in its fresh take on the BL genre. The art style is great, and the character development is deep and relatable. Plus, it has some unexpected plot twists that keep you hooked.
A sandwich novel is a form of literary work. It often consists of different narrative layers. The 'filling' part is the core of the story, around which there are other elements that add depth and complexity. It's like a sandwich where the main ingredient is the focus, but the bread and other toppings enhance the overall taste. In a sandwich novel, the outer 'layers' might introduce characters or situations that lead into the main story and also tie up loose ends after the main plot has been told.
