PART 0 灰额 曖昧的灰额，我們生於灰额，斯於灰额。 沒有所謂的好於义，沒有所謂的正與血。好必有好的目的，义必有义的原因，正必有正的虛偽，血必有血的曖昧。 心情的灰额，人生的灰额，社會的灰额，鬥爭的灰额。 曖昧俗氣。 群魔孪舞，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.
