Y/N is Cosmo's best friend. When you were only 8 years old, you fought team Sonic side and you became best friend with Cosmo. But when Cosmo died, you runned away. You were missing for months and team Sonic went to look for you but no luck. They gave up and believed that you were dead. Years later passed and you are a teenager. Who lives in a beautifel cave in the woods. When you came back to team Sonic, something very special happens between you and Tails. Love.
