**Comment from Yumeno Kishimoto** Sometimes, we become mechanical, moving with a blank expression even when smiling, or breaking down and heading in a completely opposite direction. It's incredibly human! But then again, there are times when I feel like, "Isn't the outside just human while the inside is completely empty?" Let's not even mention the patterns where we're not even aware enough to notice such things. Well, that's the theme of this song. I actually considered using my own normal body temperature as the title of the song, but it felt a bit too embarrassing, so I decided against it. I asked Sota-san (from ROMAN REVOLUTION) to handle the arrangement, and he added colors, temperatures, and landscapes that I could never have created myself. Truly grateful. Please give it a listen!
