who is he?

I woke up on a Sunday morning. as usual I woke up around 12.45 and checked my notifications on my phone to see if anyone has texted me. I needed to open some snaps and some bullshit notifications on whatsapp, but one notification caught my eye that I got thru instagram. Usually i don't get any notifications on instagram from friends or anything. It was from someone anonymous that said "sup Claire how you doing I heard some girls wanted to jump you tomorrow After school I overheard them." My jaw dropped the anonymous text was sended yesterday at 2.03 a.m. I didn't know what to do was this person playing jokes on me or SMTH? I decided to reply and ask who this person is and If there are playing a sick joke on me and who wanted to jump me.
I mean at school I was a quite kid with only 2 friends that probably talked shit about me after we hang out, but I didn't do anyone no harm I didn't understand why someone would want to jump me. But why did I care so much the first thing I got send it by someone anonymous and it's probably a joke from that one group that always picks on me for no reason. I mean the anonymous person knew my name not alot of people know my name I don't really talk to anyone And like half of the school probably doesn't even know I go there.
I puted my phone down and decided to get ready for the day so I could get some Starbucks to clear my head, I never got a message like this in my life and never expected one. As I got up from my bed and got to the bathroom I brushed my theeth and flossed them. I took a quick shower and puted on some skinny ripped jeans with a white crop top baby pink, white air forces and just puted my hair behind my ear. I ran quick down stairs to greet my mom that was sitting down stairs on the couch watching the tv. She was watching jumanij with a cup of coffee, when I came down she smiled and asked me if I Wanted anything to eat but I told her no and that I'm going to Starbucks if she wants anything?
