It's like the Dog, the Mouse, and the Bulldog.A flashback shows how Hayate's parents predicted his fate to become a strong boy who will run away from debt collectors. In the Sanzenin Mansion, Klaus just brought an expensive portrait, but Hayate points out it to be a fake, which Klaus disagrees, until a judge appears and claims the portrait is indeed a fake, leaving Klaus shocked. Hayate explains to Nagi and Maria, that his father was once an art dealer, who would use Hayate to switch a picture for a fake to package for a customer when he was little, because of that he could tell the difference. Nagi, perplexed by Hayate's apparent lack of weaknesses, plots ways to find chinks in his armor. Maria, Sakuya, and Isumi get swept up in the flow and discuss their weaknesses as well. Hayate and Wataru begin studying German in preparation for a Hakuou mathematics exam. Nagi decides to teach Wataru. While Maria helps Hayate she tells him a bit of background info on Isumi, Sakuya, and Wataru. During a flashback, Wataru felt sad that he can't enter the Hakuou Academy, since there were only three seats available for students who skip grades. But when Sakuya arrived in front of Wataru, she gave him her enrollment documents. Back in Hayate's room, they go to check on Nagi and Wataru. Wataru explains that he only loves Isumi, in which Isumi suddenly heard him. Wataru then covered his confession by telling Isumi that it was a joke, which provoke Sakuya to hit him with a paper fan for being hopeless. Nagi becomes jealous that Hayate and Maria were alone together, so she chases him while he runs away. Prompting Maria to remark that Hayate's weakness is "not understanding a female's heart".
