Not a normal High school (yanderexreader)

Sorry not sorry......

I wake up and thought about what happened yesterday. I look towards the window and I see a guy with purple hair sitting on the window seal. I throw my pillow at him and he said,"My sweet Kankei-kun.... I mean my sweet (y/n)-san." I reach for my phone and said,"I'm sorry I don't know your name?" He smiled at said,"Of course you don't we are not in the same class. I am Tsukiyama Shuu. It is nice to meet you my sweet (y/n)-san." I mumble,"Looks like that emergency words will come in handy."
-weirdo
~I'm almost there
-WEIRDO!
~I guess I'll run I'll be there any minute now.
I sigh and look up to have Tsukiyama in my face asking,"What are you doing my sweet (y/n)-san?" I respond,"I'm just-" "My lovely (y/n)! It is time for us to walk to school!" I look around Tsukiyama and see Izaya standing in my room. I shake my head and Tsukiyama said,"My sweet (y/n)-san who is this?" I feel the tension build in my room and right when they are about to fight (f/n) ran in and said,"I got you uniform let's go." He picked me up out of bed and ran down the second floor hallway and said,"I'm going to jump out of the window so hold on tight." I wrapped my arms around his neck and Izaya and Tsukiyama yelling,"Give me back my sweet/lovely (y/n)-san!" I stuck my tongue out at them then (f/n) laughed saying,"Haha suckers!" He jumped out the window and I said,"You better not try to be a ninja and jump from roof to roof!" He smiled and said,"I might." After jumping onto a few roofs he jumped into a window and said,"Welcome to my house. Don't worry I won't try anything. I'm going to be down stairs making you breakfast. Lock the window and close the curtains." He shut the door and I sighed.
He always comes to my rescue. I need to become stronger! I'm going to be stronger like him!
The door opened and he said,"Stop you little speech it is time for breakfast." I fall onto my knees and said,"Senpai teach me your amazing fighting arts!" He laughed and said,"I don't know you could kill someone if you learn it." I respond,"There are like a billion ways to kill people!" He laughed and said,"Ok then I will teach you!" I jumped up and hugged him. I thought I saw a blush on his face,but it might have been my imagination. He kissed my head and I pushed him way and my face was burning red. He noticed what he did and his face turned bright red and he said,"I'm sorry! I-I didn't mean to do that." He looked at the ground and I said,"That was a protection charm right?" He replied,"What?" I answered,"There is a rumor online about if someone that you trust with your life kisses your forehead or head it will protect you for the rest of your life." He said,"Yeah that's right. It was a protection charm." I smiled and walked passed him to eat.

I open the door to the classroom and sit down and wait for the teacher to come in. I looked next to me and saw that Ukyo wasn't there. I felt a bit safer and the teacher said,"There was an accident with Ukyo. Someone put him the hospital. He was hurt so bad that he hasn't woken up so there will be no school today. The police are going to interview everyone at the school." The door opened and an officer said,"(y/n) and (f/n) come with us." We stand and glance at each other and walk away with the officers. I get brought into a separate room than he was. I look at the officer and he said,"We are just going to ask you some questions then you can go home afterwards." I nod and the first question they asked was,"Where did you go with Ukyo yesterday?" I sighed and said,"We went to do karaoke  together. He said he didn't feel good and the next thing I know he had his hands around my throat. If you want I can remove the bandage and show the marks to you." They shake there head and said,"You can leave your a victim,but I want to know who saved you?" I said,"I don't remember...I heard someone call my name and everything went black. The only person that I called before I left was (f/n),but he said he was walking passed the karaoke building when he called me." They nodded and let me go. I wait out in the hall for him and he said,"Your story was hard to follow along with." I frowned and said,"Did you put a bug on me or something?!" He put his hand in his pockets and said,"I might have. Let's go home now right?" I ask,"Can we buy flowers for Ukyo? He was kind until his other half was in charge." He said,"Yes, but you have to promise me you give the flowers to the nurse and don't go in the room." I nod and he said,"I don't trust you so I'm going to follow you." I yelled,"I'm not a child! I can keep a promise." He stops and responded,"Sorry that I wanted to protect you." He turned and walked forward a few steps and I saw a reflection of light on his arm and I shoved him onto the floor. I heard the glass shatter and I saw the bullet hit the wall. He looks at me and said,"Are you ok!? You got glass in your arm!" He picked me up and started to run out of the school avoiding the windows.
    He opened the door to his house. He carried me to the bathroom and set me on the sink. He grabbed the first aid kit and started to patch me up. He took off the bandage on my next and said,"It is from Ukyo isn't it?" I glance away and I said,"Yeah that was a stupid question." He fixed me wounds and I said,"Thank you."
