Everyone's cover looks so creative and I don't know if I'm good enough for this, but well, what I wanted to express in my cover is... Maybe the tone of the story, almost like spoilery, but trying to be the most subtle here.
So, at first, I wanted to put all the Main Characters, but then... These two seem good enough.
I know that at first sight looks like just another BL, nothing more, nothing less. But, actually, both characters are there for a good reason, Feith is obsessed, he can forget Saliot, he can stop thinking about him, but he is very insecure and shy, he is afraid to be rejected, that's why he looks at him, he wants to be with him, but he is not sure if he will accept him. And Saliot on the other hand, is looking for an opportunity to be with Feith, he wants to be clear, he wants to be with him, he is more optimistic and he is sure that Feith will correspond with him if he shows him the best of him. Both of them are back to back because they are separated during the moment related to a "simple quest", but this quest results to be a major situation above them, represented by that crystal, and being involved so much in this situation will drag them through dark times, implying that they will struggle to be happy together when everything around them seems to fall apart.
Even the green light is a representation of good times.
