Definitely. The Hyouka light novel offers a unique and immersive experience. The world-building is detailed, and the character development is excellent.
I'm not sure specifically what 'Cap deage' means. It could be a very specific term, a misspelling, or something relatively unknown. It might be a proper name, a local term in a certain area or a very niche concept.
I'm not sure specifically as there may not be a widely known work titled exactly 'hyouka love story'. It could potentially be a fan - made or a relatively niche story. If it's related to the 'Hyouka' anime, it mainly focuses on the mystery - solving adventures of the characters, and perhaps a love story could be about the budding relationship between the main characters like Oreki and Chitanda within the context of those adventures.
