The window was wide open, letting in the breeze, which was somewhat chilly. Both of them had their eyes closed. Outside, moonlight poured in and fell on their tranquil and lovely cheeks—it was the epitome of peace and beauty.
However, if someone were to stand outside the window, or anywhere that allowed a view of that wall, they might see, beneath the slanting light and shadows, the vague outline of a person... protruding as if someone were squatting there...
Unfortunately for them, this wall was right behind their bed.
Even less fortunately, that squatting silhouette seemed to be peering down at them...
The moment they opened their eyes, they would see that protruding face, staring straight at them...
But neither of them opened their eyes; instead, they communicated by writing underneath a cup with their hands.
There's a ghost in the wall, what kind of ghost?
Ghost or human?
