Even though I knew I couldn't touch her, I was afraid of waking her up.
My transparent hand gently patted her back. I hummed an off-key tune, just like all mothers soothing their children to sleep, gently coaxing her.
"Mommy..."
She nestled in my transparent embrace, murmuring softly in her dreams, her furrowed brow slowly relaxing as she entered dreamland.
After Nana fell asleep, Stephen gently rubbed her head. When he pulled his hand back, he found a strand of Nana's hair stuck to it.
He hesitated for a moment, inexplicably, took an evidence bag, and carefully put the hair into it.
He gently closed the door of Nana's room, sat on the sofa, and stared at the almost invisible hair in the evidence bag.
In the darkness, his figure was surrounded by an indescribable loneliness and solitude.
I don't know how long it took, I saw him reach into his shirt collar and take out a necklace from inside.
His fingertips gently touched the pendant of the necklace, with a gentle and trance-like expression, completely different from his coldness in front of my grandma during the day.
Seeing that necklace, I was a little stunned.
