I-i love you!

"Sierra" Mark said waking me up I look around and I meet Mark's face he smiles "We are here" He says I nod and gets out the car and walk to the trunk Mark opens it and takes your bags out and walks to the apartment complex "hey!" You say running after Mark then you stop no need to say anything he will stop at nothing "Sierra can you grab my keys out my pocket?" Mark asked "which one?" I said "the front left" Mark answer so I get in front of Mark and go in the left pocket for his keys I unlock the door and walks inside Mark does the same but he walks up the spiral stairs to a guest room to put my stuff in then I hear Mark laughs "Sierra!! Come here!!" Mark says while laughing I run up to the room to see Mark at the door with his hands up " I swear I didn't touch anything!!" I look inside the room to see my bag on the floor open and the first thing you can see is my Markiplier shirt I smile and blush "hehe" I could only get that out "Ok then who is hungry?!" Mark yells and runs downstairs but falls I couldn't help myself I started to laugh I went downstairs to see if Mark was okay but I didn't see him anywhere so I went in the kitchen to see Mark on the floor "Mark?" I ask putting my hand on his shoulder but Mark flipped me over and now I'm on the floor I look up I'm Mark's face his brown eyes are no longer brown they are now black "Dark....." I said while getting up "yes? But why are you here? I told you not to come here" Dark said "I'm Mark's friend so I will be there for him" I said "You still have feelings for him don't you?" Dark said I couldn't say anything if I denied it he would know if I was lying "Fine! Yes I still have feelings for him!" I yell then I kiss dark
~Mark's pov~
I hear Sierra laughing when I fell then I blacked out oh no dark is out... I can see now when I open m eyes to see Sierra kissing me "I still love him" Sierra says "and you Dark can't change that" Sierra looked up in my eyes then started to blush "Mark....." She said I had to pretend that I didn't know what happen "Sierra... Oh my gosh!! Dark was out wasn't he!?" I asked standing up Sierra just nodded "Did I hurt you?" I asked looking worried "yea he flipped me over" Sierra said "That's why we were on the floor" I said "Did he say anything?" I asked "if so-" I got cut off by Sierra kissing me I kissed her back I could feel Sierra smile "Mark I still have feelings for you.... I-I love you" she said I looked at her "me too but-" I get cut off by her running upstairs
