I suggest you to read every part of Hayate Manga for the complete story (since I think you just skipped some as you always ask about chapter things). Or try to searh on this wikia, this will help you find the answer faster than asking.
The answer for this question is easily to find, Since Ruka-kun tells you the nearest chapter in the past topic (Thread:23818). You just went back 1 chapter and then you get the answer.
I'm closing this thread now, since the questions have already been answered.
