The world is not only peaceful as you see it.
——Inscription
Su Yu's first nineteen years were uneventful. She has been what adults call "other people's children" since she was a child. She is well-behaved, sensible and has excellent grades. Life for her was smooth, peaceful, and... Meaningless. It wasn't until later that she discovered that this world was so dark and bloody, and that there were so many terrifying monsters hidden in this world... Su Yu felt the heat for the first time.
