S1·E40 New Year's Food is Also Good, but Enjoy Hayate, Too

On the night before New Years, Nagi orders Hayate to bring her to Kujukuri Beach to have a romantic date watching the sunrise after reading about it in a manga. Hayate is forced to take her on a bike since he is not old enough to drive. He manages to make it on time, but Nagi falls asleep just before the sunrise. The next day, the mansion's circuit breaker overloads and Hayate goes to the annex to turn it back on. On the way there, he gets stuck in a blizzard which is really caused by Sakuya's snowblower. He manages to turn the power back on, but passes out due to the extreme cold. After insulting Sakuya without meaning to, she (and her bodyguards) ditch him and leave him on a stretcher in the annex.
