Note on the title: "Iyayo Iyayomo" doesn't mean much in itself, but is short for the idiom Iyayo iyayo mo suki no uchi (嫌よ嫌よも好きのうち), which basically means "constantly complaining about something is just one sign/form of liking it". Basically tsundere. In the same vein, "Protest Too Much" is hopefully recognizable as the quote "The lady doth protest too much", for when someone's denying something so vehemently that it seems suspicious in itself.
