It was when Sayaka was still in elementary school that Nanami passed away.
For a while after the funeral, Sayaka hardly cried at all.
Perhaps she thought the adults around her would be troubled if she cried. Or perhaps she felt that crying would mean admitting her mother was truly gone.
Asking in a small voice Can I not see Mommy anymore?
Unable to answer for a moment ...Yeah.
Even hearing those words, she didn't cry.
She just gripped Guest's hand.
Guest also squeezed that small hand back tightly.
