Why am I feeling emotion? (Saikixreader)

Chapter 10

Time skip to the next day at school
Your POV
I walked to my bus stop and see a pink haired boy standing before me. He hears my footsteps and turns to me. "Y-N." He smiles slightly at me and my heart melts. The bus approaches, and we walk on, holding hands. The boys on my bus glare at Saiki, as he just stares at them, a neutral expression plastered on his face.
We sit down and I feel a hand go around my shoulder. I look over and Saiki is blushing slightly, with speckles of red dusting his cheeks. He kisses my forehead as he catches me looking at him. His lips lead down to my lips and then my neck, sucking my skin and nibbling slightly, still silent. I try to hold in my whimpers of pleasure. He leaves a hickey on my neck. My face turns red as he moves away from me, his face still neutral. The bus arrived at school, and I looked at Saiki. "Don't you usually walk with Nendou and Kaidou?" He looks at me, and nods. "I'd just rather be here with you, Y-N." I look at the necklace from last night on my neck and blush.
We walk off and go into the school. He holds my hand as Nendou and Kaidou walk over.
"Hey buddy! Why are ya holding Y-N's hand?"
Saiki glares at Nendou when he says this.
What an idiot.
I hear Saiki's voice ring in my head, and a confused look shows on my face.
Y/N, I'm a psychic. I know this is a lot to ask, but don't tell anyone!
I nod my head slowly, swallowing the pill of his words.
He's a psychic?
