I must say this is one of the most beautiful VNs I've played; it's very well made too. It was very apparent how everything was made with so much care, from the design, characters, OST, and story down to every detail.
I love how the narrative implies a deeper story than what is portrayed, and the wistfulness of their interactions is unusually delicate to the point that it almost feels ethereal. Overall, it is a very lovely game.
