This is really great...I just love people that post good poetry on here. I think the imagery that you use is wonderful. Great job. I absolutely adore how you make the moon both ruthless and so longing. The sun is curious and helpless. Kudos!
One thing that is kinda funny is that this kinda reminded me of the movie "Ladyhawke" from the 1980's with Michelle Pfieffer and Mathhew Broderick. I don't know if you have seen it (have no idea about your age, after all) but you should check it out to see what I am talking about.
It is a well written, descriptive poem and I am lead to assume that the moon refers to Sess, while the sun is Kagome. Though they are never mentioned by name, your intoned stanzas do well to describe their personalities.
This was very well done, your imagry skills are very impressive. The emotion were also very well conveyed, all in all a very well written piece of poetry.
