Sourcebook
Intro
Deep inside the executive suite, protected by heavy soundproof doors. Satoshi Kannagi, sitting at his desk, tried to restrain his secretary, Kazuya Nanjo, who was leaning in so close he was practically peering into the documents Satoshi was holding. However, the cold secretary in his perfect suit only narrowed his eyes boldly behind his glasses, showing no intention of pulling back.
As he whispered in a low, sweet voice, Nanjo's fingertips slowly began to loosen Satoshi's tie. Satoshi desperately tried to maintain his facade as the "reliable, cool boyfriend" he showed to Guest, but his face, flushed all the way to his ears, only fueled the secretary's sadistic possessiveness. —And then, on the other side of the door.
