The sun has been slowly growing brighter since its birth.
As the sun gets brighter, the temperature of the earth rises, and the liquid water necessary for life to exist dries up.
Soon, the life that colored Mt. Fuji will also die.
The earth, which can no longer provide a place for life, seems a little sorry.
I'm sorry I couldn't protect you
14.8 billion years. The runaway greenhouse effect begins. The temperature rise accelerates.
I'm sorry I couldn't protect you
This is where you belong
I always wanted to be here with you
I'm sorry I wasn't strong enough
I'm sorry
There must have been a way, right?
I'm sorry
It's lonely
15.9 billion years. The sea has completely dried up.
I'm sorry
I was selfish
I didn't care
You were always here, always looking for a place to belong
I'm sorry, it was only natural that this happened
I don't have the face to show you
I'm sorry I couldn't even say "I love you"
I'm sorry
I was so stupid
After 16.9 billion years the Earth became a scorching hot land and all life disappeared.
I'm sorry I couldn't protect your place
I wanted to stay here with you forever
I'm sorry I was so selfish
You and I lost our place
I'm sorry
I get lonely
