Gyaru Bitch na Do S Osananajimi ni Choukyou Sarete Dorei ni Natta Boku

My name is Kouji Onoda.
When I was little Alice Aikawa bullied me. My life was a nightmare.
Something happened with her parents, work or something, and she moved away.
Everything was better after that. I studied more, got into sports, made friends. I even got on the student council.
Then one day, six years later, she came back.
Her voice and her style had changed, but I instantly recognized her. And like the trauma of my childhood, I could not escape her...
