For Your Sake, I'll Give My Best Blasting Through Everything
Nagi tries to gain experience after her work was rejected by a manga magazine. She believes she has no experience being lazy and staying in all the time, despite being rich and thus not having any problems living. She asks Hayate who has extraordinary experiences, but then becomes angry when Hayate tells her he once won a 'Manga Newbie Award'. She continues to gain experience while attempting to clean the house (which she messes up terribly) and by trying to serve food.

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.
