Mistakes were in fact made

I stood there with my head facing down ashamed of myself. I couldn't muster up the courage to look up. Right then, my head was pulled up by my hair and I came face to face with Natsumi-san and another sharp pain surged through my other cheek. 

"This is for pissing me off and getting me so worried," she said and my lips start to tremble. "I'm sorry" I wanted to say that over and over but no words were leaving my mouth.

"No need for that," she said and then pulled my head into her chest hugging it tightly. I could feel her warmth touching my body and felt a similar feeling. A feeling I forgot about. It had been that old. "I know Kazuki, I remember what day it is," she hugged me tighter and started patting my head. 

"It's okay Kazuki, let it out."
