Koi to Yobu ni wa Sasayaka desu ga

High school girl Umi Sayama is placed in the care of the neighboring Hiroi family while her mother is away on a long business trip. The Hiroi household is home to Shouya, a guy eight years older than her. Umi admires him, and her heart races at their long-awaited reunion. But the Shouya she encounters is completely different from the one in her memories...

A faintly sparkling cohabitation story about meeting changed memories once more.
