Analyze This -Analyzing My Boss's You-Know-What-

Reiya Mizuki has a special ability. He is able to "ANALyze" whatever is put inside him. His family was torn apart after his father committed suicide because of the Serizawa Group and he wants revenge. He becomes a corporate spy and starts working for the company. His main target is the heir to the company, Kento Serizawa, the new director of the sales department. Reiya wants the top-secret clientele list that Kento has, so that he can leak the information and destroy the Serizawa Group. In order for Reiya to get his hands on the information, he needs to seduce Kento and make Kento fall for him. But Kento isn't easily charmed by Reiya's seduction and things are proving to be more difficult than he expected.
