They should've redistributed the parts by giving some singing parts of Rei to Gaeul and instead have Rei do the entire rap. The switch from Rei to Gaeul makes skill gap very obvious and totally doesn't benefit neither Gaeul nor the song.
I like how in Gidle songs Soyeon is the one who always raps, no matter how long the rap parts are. It is better to have fans complain about line distribution than ruin the quality of the song by trying to have equal distribution.
