主人公叫袁徠,袁朗的書名叫《[士兵同人]灰色地帶》，它的作者是吳驊創作的BL、科幻、戰爭型別的小說，內容主要講述：PART 0 灰色

曖昧的灰色，我們生於灰色，死於灰色。

沒有所謂的好於壞，沒有所謂的正與邪。好必有好的目的，壞必有壞的原因，正必有正的虛偽，邪必有邪的曖昧。

心情的灰色，人生的灰色，社會的灰色，鬥爭的灰色。

曖昧俗氣。

群魔亂舞，真實無比……

This is our gray world.

It looks like a helix,no one can escape.

But，we together, together, against it together.

I could not promise to love you forever, because I don't know what’s happen during my whole life.

But I can catch your hands, through this world.

Trust me, never give up.

Our fear, our betrayal, our harmfulness.

Our world, our life, our love.
