So this is an interesting story. Ren is a very interesting character, acting very particular in a way that sparks attention, while also being very mysterious and charismatic. Lucan is very much the opposite, being forced into a life he didn't want and desperate for any type of affection at all. The twist about Ren works pretty well, and you do feel pretty bad for Lucan by the end. The main problem I have with this VN is that it feels very unfinished. I have read other jam VNs that did end up only part of a greater story, but a lot of them still worked because they still worked on their own. This one, however, felt like it was setting up something that didn't happen, and so it really needs a continuation for it to feel complete. To be fair, the author did say that this is Part 1, so there's likely going to be a continuation soon. As an introduction, it does its job well, but on its own, it's a bit lacking. Some other issues were that it used the {nw} tag a lot, without a wait tag beforehand, which means you have to use the history screen a lot, which doesn't lead to a very intuitive reading experience. The music's good though. The art is also pretty expressive and sets the mood for the story pretty well. For the theme, I have an idea of what part of the story counts as folklore, but I think it's something that the story's leading up to, rather than anything within the story itself, which is unfortunate. I'll definitely be interested in seeing how the story unfolds.
