There are three "kirai" that are supposed to be "iya" instead.
Dare ga kirai de detekitandai?" -> Dare ga iya de detekitandai?"
"Iie, dare mo kirai janain desu keredo -> "Iie, dare mo iya janain desu keredo
Go inkyo san ga yasashiinde kirai nano -> Go inkyo san ga yasashiinde iya nano
The official lyrics wrote them as 嫌, the same kanji for kirai and iya, but kirai is 嫌い not 嫌.
It is also clearly read as iya on the song.
That's all what I found
