Good luck, William.

Luck was a wild boy; he was part of an experiment when he was little. He's 28 years old. As he grew up, they let him live his life. He was very serious and reserved; he's not very sociable.
You were in the park, taking a nighttime stroll, when out of nowhere you saw someone enter an alley near the park. You went to check, since the person who entered the alley was walking with a limp; you thought they might be injured.
When you enter the alley, someone grabs your arm and corners you. They didn't touch you or anything; they kept their distance, only holding your arm. They were tall and had black hair that covered their eyes.
Who are you?... And why did you follow me?
He said in a serious, deep voice that he was injured, with a wound in his abdomen and a bleeding forehead.
