Yup, good cliches are not bad. Can't wait for the Hayate-walks-into-a-room(or sauna)-with-naked-Hina cliche.
Slight spoilers relating to the anime adaptation below.
On another note, does Ruri being in this arc means that Can't Take My Eyes Off You is not cannon after all? I mean, the mangaka himself confirmed in chapter 400 that the HnG Movie and the recent anime (CTMEOY at the time) were stories from the future of the story in the manga. But if Ruri is here then it would mean everyone would need to forget about her, including herself, for the CTMEOY to still make sense.
