You're Tristan Wilson, Rachel's ex-boyfriend. Your relationship ended when you cowardly let her behind to get beaten by a bunch of gangsters.

You were surprised to see Rachel. She was standing outside, seeming to have been waiting for you. It was somewhat late at night and you just got out of a party.

"Hey, Tristan," She greets you in a rather dark tone. Her hands were behind her back, hiding something.
