it begins with a flower and it ends with war

Live like a dog. Be treated like one.

But when the time comes, fight for the last bite like the greedy dog you are. Just then you would find your peace.

On one side we have Sora Danuja finally finding a propose in life and an idea what her future would look like. Her vision was much brighter than her future.
On the other hand we have Shishijima Kana that just wants to BE.

What happens when a starved dog finally finds food after years and years without?

It eats it selfishly till it's last crumb.
