Along with our worries, there was also our youth.

The not-quite-sequel, not-quite-prequel, not-quite-alternate-ending to Yoshida Motoi’s celebrated "Natsu no Zenjitsu", "Mizu no Iro Gin no Tsuki" continues the melancholic stories of love and loss that weave through the maturation of Mori, Hanami, Aoki one year later…
Mori, a cheerful playboy in his sixth year of college, has just fallen in love with a high school girl named Hoshi. From that starting point, Mizu no Iro Gin no Tsuki portrays the relationships among Mori's friends and acquaintances.
