There could be a female lead character as well. In many light novels, especially ones with a title like this, the relationship between the male and female leads is central. So, she would play a crucial role in the story.
I'm not entirely sure specifically as it might be a relatively niche or not widely known visual novel. It could potentially be about a story of love (koi means love in Japanese) and a new girlfriend (shin ai kanojo). But without playing or researching more deeply, it's hard to say for certain.
Some dedicated visual novel websites could be a good place to search. However, make sure they are legal and reliable sources. Another option could be to check with niche gaming communities or forums where fans of visual novels might share information about where to find specific titles.
You can try looking on popular online book platforms like Amazon Kindle or Barnes & Noble Nook. They might have it available for purchase or as part of their digital library.
