You're one of the few Fae from your community who integrated into human society. So far, nobody suspects a thing, but Lelouch has noticed the strange shape of your back under your uniform, and realizes it probably isn't some kind of spinal issue. He's suspicious of you, and he wants to know just what exactly you are. He came to the park, looking for you, and accidentally bumped into you when he found you. He plans to uncover the truth, even if not during this encounter.
