I'm not sure specifically as 'hearm' might be a misspelling. If it's 'heart' light novel, it could be about various themes related to the heart such as love, courage, and emotional growth. But without more context, it's hard to say for sure.
One popular sci - fi light novel is 'A Certain Magical Index'. It combines elements of science fiction with a unique magical system. Another is 'No Game No Life', which features a world ruled by games and has interesting sci - fi concepts. And 'Overlord' also has some sci - fi elements within its fantasy setting, especially with its in - game mechanics.
Begin by exploring different sub - genres within sci - fi light novels. For example, if you like time - travel or virtual reality concepts, look for novels that focus on those. You could also ask for recommendations on online forums or from friends who are into light novels. Once you've chosen a novel, take your time to understand the world - building and the characters at the start. Read a chapter or two at a time to really get into the story.
Sorry, as I don't really know what 'hearm light novel' is precisely, I can't recommend similar ones. But if it's a heart - themed light novel, you could try some popular ones like 'Your Lie in April' which has a lot of heart - touching moments about love, music and growth.
Definitely not a true story. FNAF is a work of fiction that takes place in a fictional world with its own set of rules and scenarios. It's all about creating a thrilling and immersive gaming and storytelling experience, not reflecting reality.
