A bad end no matter what you do. A good end cannot be found.
Can you save them? Or will it all end?
Heaven if you win... Hell if you lose. An ultra-harsh life.
Can you save Rako Otonose? Protect her from Mika. Never let the engagement be broken.
A world where every struggle leads to a bad end... A good end does not exist.
Even in such a world, I want to find it. The "Good End." Bad end? I don't even know the meaning of those words.
This is the story of two people...
♡The Beginning of the End♡
You belong to me♡ Don't run away, okay?♡
If you run, I don't know what will happen to you...♡
Don't run. Don't leave. Don't avoid. Don't cling.
