This was an amazing prequel to the original series. It tells the story of Kijima and Kido from the prospective of Kido. It tells the story how Kijima first started writing porn. Kijima who was a genius and Kido who was jealous of him cause he was perfect at everything realized that they are actually more similar that they thought. During their hardships they find comfort in each other but because of lies and deceits, they are just not meant to be. But they work things out and still stay as friends and co-workers. Really wonderful.
