Absolutely amazing.
If you saw this and think it might interest you, please read it. It's really short, only took me about 3 hours, but it has made me feel the most invested I have ever been in a book/visual novel. I don't usually like reading romance and yet this has made me feel intensely emotional. The characters and settings are surprisingly in-depth in terms of personality given how short it is, and everything, from the music and the exceptional art to the writing style reflected in each scene only serves to enhance the emotions felt in each part of the novel.
Please read this novel, you won't regret it.
Btw I started reading at 9 pm and it's now past midnight and I have just finished reading it. I thought I was just going to read for a while and finish tomorrow and got carried away by the narrative.
