In otome dori - related works, excluding adult fiction, there is often a strong emphasis on emotions. The female lead experiences a range of feelings from love, friendship, jealousy to self - doubt. The narrative might be slow - paced to fully explore these emotions. The setting and the secondary characters are designed to enhance the main character's journey, with each interaction adding to her development and the overall story.
Since 'otome dori' can imply a certain charm or allure in the context of storytelling, but excluding the adult aspect, there are some YA (Young Adult) novels that could be related. These novels usually feature strong female characters and romantic elements that might resonate with the otome dori concept. One could look into series like 'The Selection' which has a princess - like selection process and elements of courtship that share some similarities.
Since I still don't have enough information on 'Do dil bandhe ek dori se', I can't give the exact story details. But if it's a love - themed story, it might follow the common pattern of two people meeting, having some challenges in their relationship, and finally coming together. For example, they could be from different backgrounds, and society or family tries to keep them apart, but their love overcomes all.
I'm not sure specifically as it could be a rather niche light novel. It might be about some kind of isekai (another world) story, perhaps involving a character's journey or adventure in that world. But without reading it, it's hard to say more.
You could try looking in specialized Japanese light novel stores, either physical ones if you're in an area that has them, or online stores that carry a wide range of Japanese light novels.
