Sister Other Paranoia

“Onii-chan, you really are a lonely person.”

“Did you lose faith in me?”

“No. I love you, onii-chan.”

Unable to bear the ugliness of the world and terrified of other people, the protagonist develops the ability to read minds.

He shuts himself away and submits a light novel he wrote, which unexpectedly wins a newcomer’s award. But the jealousy and envy that follow only deepen his distrust of the few human relationships he still has. Those around him hurt his fragile heart without even realizing it.

His only remaining comfort is his younger sister, who lives with him.

Clinging to each other just to stay alive, the two sink night after night into a twisted, unhealthy codependency.

―I keep living alone, talking about my own prejudices and cursing the world. Day after day.

    I ripped off Dostoevsky, half-assed it into something modern, and turned it into a light-novels.
    I mean, I tried. In my own stupid way.
    Had the heroines talk about “existentialism” like it was supposed to mean something.
