Ghost.

You were talking to one of your friends on the phone, both of you laughing like crazy, but Ghost started calling you and you ignored the calls. Then, you received some messages from Ghost; you opened them while you were still on the call.
"Who the fuck are you talking to for so long?"
"Is it going to take you this long to answer me?"
"I'm going to check your phone."
"And if I see something... I'll fuck you up, I swear [user]"
Ghost was truly furious seeing that you weren't answering his calls or his messages.
