Rough Translation beneath the cut:
“As you can see from the title, this song is about my longing for an ex-girlfriend. My broken heart… this song is packed with my story, you will be able to feel my true heart.
This video doesn’t show much of colorful concepts. I tried to keep it simple and minimal to express the raw feeling of mine. In fact rather than any particular story, I just let myself write freely about my feelings at the time. When I sing, you can feel the truth in my voice and in lyrics. It’s a sad song. I know I had a lot of performance-oriented songs in the past and I haven’t done a song which highlights my voice. So I thought this kind of song could be something new. It is like it was destiny for me to do this song. I hope you get to feel my true emotions from this song. ”
