T@gged by the lover or killer

Chapter 1

My POV
"Hailey I found out that Jake is gonna be at the party! Did Rowan invite him?"
"Yea Sarah she did which is weird since Elisia doesn't want them hanging out anymore!"
I walked out of my sisters room and went back downstairs to watch some tv. My phone buzzed and it was from Sean
Message from Sean😜
Sean😜: Hey Sarah!! What are you doing Friday?
Me: Going to a party! You?
Sean😜: Same!! Which party are you going to?
Me: My sister's party!!
Sean: Same girl! See ya there!😉
Me: see ya Friday!!
I turned my phone off and went back to my show. I felt it buzz again and I saw Sean's name pop up so I knew it was him. I ignored it and kept watching. I got another message but I wasn't sure who it was since I was too lazy to pick up my phone to check. I was pretty sure it was either Ash or Brandon, but no one can be 100% positive when it comes to messages.
"HAILEY WHO IS xxx-xxx-xxxx???????"
"I think it is Brandon but it might be Jake!"
"Ok thanks!"
"Wait what did it say??"
"It said hey babe see ya soon😉😉😉"
"I think it might be Brandon sis!!" I froze. How did he get my number?? I used to date him until he bullied my friend Rowan. He also cheated on me so there is that. I decided to respond to him knowing that it would freak him out.
