Haiiro no Umi nite Kimi wo Matsu

I walked along the beach in leather shoes, with my feet getting stuck in the sand.
The season is autumn. October. A comfortable temperature, neither hot nor cold.
I was with a third-year senior named Rin Sakuma, walking by the sea, where I couldn't swim because it was out of season.
Perhaps because the weather wasn't so good, the sea was dark and murky, reflecting the gray sky and forming waves.

A sad short BL visual novel about a senior and his junior.
