Honestly I think this single is great. And well done. All of these songs also flow together well and create their own darker environment for this single which I like. I'm listening to them again, and I haven't enjoyed her ballads this much in a while. Zutto... is definitely the weakest but still an okay ballad. Just okay. It sounds a basic ayu ballad that I'm never going to listen to. The last two are more special in my opinion and I get rock influence with last minute, god bless. I'm just glad that everything feels darker than anything in a while. And the lyrics are amazing.
