Number Fifteen thought to herself but didn't act rashly. Instead, she raised her hand and tapped lightly under the bed.

The curtains weren't drawn tightly, only a thin layer hung down, like a layer of mercury moonlight pouring in through the sheer curtains, the room's light wasn't dark, everything could be seen clearly.
Number Fifteen cautiously approached the side of Phoebe's head, eyes wide open, carefully leaning near his body.
