All is fair in love and war

Let me tell you a mathematical story.

x+y but y+z
in order for xy to happen,

xy=-z

but z-y does not equal to y+x

the only way for all to be equal,
x-(yz)=y-(xz)=z-(xy)

It means that to achieve equality in the game of life so named after Love and War, we must all be lonely and without anybody.
They say that all is fair in love and war.
That, my friend, is a LIE.

To win the game, you have to use realpolitic. That's why it's all fair in LOVE and WAR. Because in the love game, you use exactly the same strategies in wars.

It's a sick game that devils play with a tear in their eyes for even they know how cruel mankind is.

The story is really simple. It's a love triangle. X likes Y but Y likes Z. So, can you understand the story now?
