"There is no good person in this book, and there is no winner. You will not be able to get out of this book after reading it for three days, so enter with caution." Love is real, and so is betrayal. Trust is real, calculation is also real. They exist at the same time, and this is the most despairing part.
Be prepared: it won't give you a warm hug, it will just dig a hole in your heart. But in that hole, you may be able to see something clearly, about the price of forgiveness, about the shape of obsession, and about how difficult it is to "let go". I will spend the rest of my life regretting missing you.
But again, I would light that fire.
