In the quiet solitude of her room, Ayase Imaizumi, a shy art streamer known online only as "Pinkie", crafts vibrant worlds with the stroke of her digital brush. Life outside her screen is much simpler: she's just another freshman in senior high. But an unexpected email from Kurotsuki, a rookie light novel sensation, turns her world upside down. He wants her as his illustrator and co-writer. "Be my illustrator and co-writer for my next novel." Suspicion swirls, but her ultimate curiosity leads her to the grand halls of Hikari Suisei Publishing. To her shock, Kurotsuki reveals himself to be Keiyu Kurumizawa, her classmate from middle school; a charismatic genius with a cold smile. Yet, beneath their reunion lies a shared, shadowy past, a puzzle that the two of them must untangle. Can they write and draw their way out of their troubles and into a bestselling light novel, or will the truth tear their partnership - and them - apart?
