The studio versions of this song, Watashi no Koi wa Hotch Kiss, & Tenshi ni Fureta yo! are the only in-universe songs that feature an acoustic guitar, though none of the girls have been shown to own one. The reason for this is because these are also the only three songs that are played as a four-piece band, without a rhythm guitarist, with Azusa, Yui, & Azusa being absent from each of them.

The acoustic guitar is used so that the song has the rhythm guitar it's supposed to have, while at the same time showing that it was never played that way, the acoustic being a bridge between having and not having that position played. A ghost rhythm guitarist, if you will.

Note 1: Sawako may have been shown to be playing rhythm on Watashi no Koi wa Hotch Kiss, but there is no rhythm guitar in the live version of the song. The decision to have her play was likely made after the song was recorded.

Note 2: Fuwa Fuwa Time also has a four-piece version, but it simply lacks a rhythm guitar, even in the studio version.

Note 3: The four-piece versions of the out-of-universe songs ''Cagayake! Girls and Don't Say "Lazy"'' actually lack the lead guitar, not the rhythm, likely because there's little lead in either, and both would sound very odd with the rhythm removed instead.
