At my fifteenth birthday party, a mysterious old man gave me a pair of walnuts engraved with human faces.
>That night, Walnut moved his lips under the moonlight, and black mist appeared on his deskmate.
>In math class, the teacher suddenly lectured with a noose around his neck.
>It wasn't until I looked in the mirror that I realized that my eyes were dark.
>The two faces on the walnuts are overlapping and smiling in my pupils.
