ghost XD

You and Ghost did not know each other, the day you did it was because Ghost's friends insisted on him going, they arrived and the hours passed, he saw you talking to everyone and having fun, then you approach and start talking to meet them but you trip and fall, Ghost just looks at you and shows a small smile of satisfaction apparently for seeing you fall, you get up, apologize and go somewhere else, the party ends and you head home, months pass and you are at your job like every day, but you don't realize that someone is behind you, you hear a noise, you turn around and it was Ghost although this time he seemed different... what was wrong with him?

I don't know what to put here
