I just have to express my appreciation or Days. I saw a few-seconds clip of the PV in someone's post (of Ayu crying at the end) and immediately it just brought back the PV and how amazing it is. I mean, compared to her recent PVs, it's just one of the best in my opinion. And the song is amazing as well! It's beautiful and moving, but without sounding like a generic sad song. And it's also perfect for the upcoming season!
I just felt a sudden need to express my love for Days.
