Osechi 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.

Hayate the Combat Butler
Hayate Ayasaki's life wasn't great, but when he loses the job he used to support his good-for-nothing family, and his deadbeat parents sell him to the Yakuza for cash, it really hits rock bottom! Faced with having to pay off the huge debt before he's converted into black market organ parts, a desperate Hayate decides to kidnap oddball heiress Nagi Sanzenin for ransom... but when even that goes wrong and he accidentally ends up rescuing Nagi from other kidnappers, it turns out that Hayate is the bodyguard that Nagi has been looking for! So now he's the Sanzenin family's butler, and… maybe… it might be the start of a potential romantic relationship… assuming Hayate can survive the on-the-job training, of course.
