On her 40th birthday, Yumeko's grandmother died. She was left all alone. She had no family, no boyfriend, and was working as a temporary worker. That's how Yumeko celebrated her birthday. Just as she was wondering what to do next, her in-game lover, Sierra, asked her to move in with her.

Surprised by this sudden turn of events, Shiori tearfully confessed to Yumeko, "I want to be with you."
