I actually love the song. I think people are being so critical because they are treating these as an ayu song when in fact it is not; it is Naoya's song. ayu made the song
for him in his style. Despite that it does have some very ayu elements to it like the orchestral intro and the piano pieces throughout. And about all the Heartplace "rip off" comments, ayu has referred to similar elements in her previous lyrics all the time (for example Sparkle's chorus is literally just an extension of Catcher In The Light)
People need to stop being so negative about ayu's recent work all the time. It seems they are never happy with anything she does anymore
