In only a couple of days after the online detective Amelia Holmes enrolled, she made a video titled 'Shenanigan', revealing secrets of White Book and exposing the student council's corruption. So after two years as the president and the centre of White Book's crime--smuggling, sabotaging, blackmailing, forging and framing--his era had ended. He fell into the abyss of despising and isolation. But his influence was still alive--mystery after mystery keeps popping out. Three months later, Amelia convinced the former president--known infamously as the shenanigan and a stalker--to become her assistant. He only agreed as saw an opportunity to make his harem's dream possible. The two with completely different energy--golden right and suicidal dim almost--sat in their little book club. They knew mysteries in any figure could appear anywhere and anytime. As if a harem of mysteries they got into. Did you know?: The cover is not mine, but a great artist on Pixiv @有本 亘. nice symbols.
