The Guy Who Stole My Heart and Mind (A Mabill Fanfic)

Bill?!

I don't own anything but the story

Previously on TGWSMHAM
He looked at me with a sad face "Mabel....were you just throwing up minutes ago?" He asked sadly. I gulped, not knowing what to say. "Mabel, you're beautiful, you don't need to do those things. Your brother told me everything" he said that made me widen my eyes. "Shooting Sta-" he covered his mouth after spilling out my nickname that bill gave me.
"B-Bill??"
...

I widen my eyes, staring at the blonde male who called me Shooting Star. "B-Bill...but how? Why?" I kept blabbing non stop, making him growl. He was annoyed. "I don't know exactly how or why but I am..this, a human" he said, sighing. "Now Shooting Star, answer me this. Why are you doing this to yourself? Is it because of big blonde mouth? She's mean of course but why do you care about what she says about you? All those things that she said are lies, you're beautiful, smart in your own way, everyone loves you, why do you want to disappear when your family and friends don't want you to, they don't know do they?" He asked me. I looked down, tugging my left sleeve as tears were forming "n-no..." I manage to whisper.
"Pardon Shooting star?" He asked to me, waiting for an answer. I was. About to answer the blonde dream demon but then Dipper came into the room "what's taking you guys so long? Stan wants all of us downstairs now" Dipper said and walked down to Stan, who was sitting at the dinning table, waiting for us.
I sighed and was about to walk out of the room until Bill grabbed my arm, causing me to whimper in pain "if you want to talk, come to me. I'll help you, my shooting star" he said and leaned forward, placing his soft lips on my cheek. My face bursts into pure redness and I looked away "c-can we go to Stan now..." I whispered and walked out of the room and down the stairs towards Dipper and Stan.
I looked over at Stan "Yes Grunkle Stan?" I asked, not knowing that my left sleeve was up my Elbow exposing the horrific deep, reddish purplish scars. "Well I was about to say that- Mabel...your arm...what happen?! " Stan asked me, staring at me with sad eyes. "I...um.." I tried speaking but gibberish came out of my mouth. Tears were forming and I ran out of the shack in tears. "Mabel!!!" I heard Bill yell, he's probably chasing me. "Leave me alone!!!" I screamed in tears and ran into the forest, sitting under one of the trees, sobbing on my knees.
How am I suppose to tell them?
