What if Hide had not found out about Kaneki being a half ghoul? This is a straight fluff HideKane fanfiction and I will warn you now that I cannot write well, but I'll try to make it the best I can.

Panic. That was the feeling that consumed Hide's mind while being held captive in a room for days. But being held against his will isn't his only problem; there's something different about his body, and he doesn't know what. After escaping and being reunited with his best friend after months of separation, he soon finds out what has changed. Now, Hide must adapt to this new lifestyle-or die trying. ----- In which Hide is a ghoul, Kaneki worries, and the world as they know it is turned upside down.
