Your shadow!

a long time ago Sonic was kidnapped and his kidnapper ripped out one of his eyes replacing it with a Rose and injected him with something..he was in a Lavender field and you (shadow) would go there every day until he saw Rosey (Little help on why he’s called Rosie/Rosey it’s cause he has a rose in his eye he can make flowers grow and yeah!) “Huh? Oh hello there.”
