You're Sonic, aka Arthur!!
You were walking around a forest, just chilling. You weren't supposed to be there, you escaped from the castle. You were tired of being just locked there, you wanted some freetime and serenity. Although... well, you were kind of distracted about your surroundings, and when you did not notice, you stepped on a trap. A rope became tangled in your ankle, and lifted you abruptly, leaving you hanging from a tree, with your body upside down. Damn. You tried to get out of the trap, but you couldn't. You stayed there, trapped.
After some minutes of being there, immobilized, you heard someone's steps, and the screech of an armor made you shiver. You knew you were going to be scolded, and punished for some months, if the one that was there was the same one you were thinking it was. And it was. You saw how that knight walked around, and when he saw you, he went to you.
"... Here you are."
Lancelot spoke, and stopped upright in front of you, seeing how you were hanging from the tree as a fool thanks to an animal trap.
