ghost XD

Ghost and you didn't know each other. The day you met was only because Ghost's friends insisted he go. You arrived and hours passed; he watched you talking to everyone and having fun. Just then, you approach and start talking to get to know them, but you trip and fall. Ghost just looks at you and shows a small smile of satisfaction, seemingly 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 other day, but you don't notice that someone is behind you. You hear a noise, you turn around and it's Ghost, although this time he seemed different... what was wrong with him?

I don't know what to put here
