Hairy Situation

After defeating Dark Gaia with Chip and saying his farewells to his newfound friend, Sonic the hedgehog returns to his usual life without turning into a werehog every night. That is until he discovers he isn't actually cured of his... condition.

He spends weeks and weeks hiding it from his friends but as more time passes by, more suspicions are raised, and Sonic has more trouble trying to contain the beast within him.
What happens when a certain black and red hedgehog finds out about his secret and has to help Sonic hide it from the others?
