Hayate, Chiharu, and Ruka arrive at Hakuou to teach Ruka how to ride a bike. Hayate gives Ruka a choice between a kind lesson or the harsh one. Ruka chooses the harsh lesson because it would give her time to sleep for her job. He shoots a water gun at her telling her to call him Coach. Chiharu came alone thinking that Ruka had a thing for Hayate but went off the buy some tea. Hayate ties Ruka's hands onto the handbars and puts her on top of a steep hill. Hayate pushes her off, and when the bike bumped off a rock, Hayate grabbed the bike to keep it from falling off. After giving her words of assurance he said to do it again. Ruka laid on a tree to rest swearing to get back at Hayate and shoots him with the water gun. Chiharu comes back, thinking that Ruka may have a thing for Hayate. The next morning Nagi asks Hayate to teach her how to ride and Hayate gives her the two choices. Nagi picked the kind lesson.
