Hikki admits that she couldn't dance. There's not much choreography in her past videos. This PV has the most dancing. I can't help but feel that she's making a fool of herself by dancing, it's her one weakness. Maybe she'll learn how to dance. She already knows how to hold a microphone
We already agree that this video is for her fans and it's a goodbye song. I think it's called Goodbye Happiness, because we are her happiness.

About the doves in the pizza box. I think she's waiting for new inspiration. The dove also represents the Holy Spirit. I think Hikki composes such good music because it is a gift from God. She said her favorite song is Hikari. To me God is the Light that will be with us no matter what. He let the light out. Only one doves stays with her, the rest fly away. Hikki's a dove too, full of light, maybe she wants to find a new partner. (please let it be me)
