<report>Every encounter is a unique one out of 6 billion possibilities. It really shows us how fast global population can grow. I wonder why
Kataoka Tomo didn't change the number to 7 billion, when it was ported to PC in 2014 to make it more relevant.
I came to know this after going through Narcissu's soundtrack. One particular BGM Sakura struck me so hard that I began searching for the source.
Summer and Autumn were both vanilla romantic-ish. Winter and spring however were much deeper. In Winter, the protagonist's chance encounter with Koyuki reignited the "dream" he once believed to have lost. While in Spring, Hazuki helped the other protag once again find his place in the real world.
Typical of Kataoka, unpretentious yet evocative. A decent reminder of what I have lost and yet to regain.
