This is a story about love and hope, a story born out of resentment and flag.
Green song? Reject.
Being backstabbed by someone you admire? Reject!
The Aige here seems to have a one-in-a-billion chance, and it seems that she is a visitor from another world, Shajo Aige, who has the name of "rationality". Apart from reason and order, there seems to be no difference from love songs in other worlds.
.... No, there is probably still a difference - at least there won't be this large golden retriever that can't be driven away.
If the strongest Master in the Xingyue World is no longer a love brain, and if the Root Princess is no longer neutral and evil, will the story be different?
