Reborn: Seeking Justice from the Heartless Homeroom Teacher

In senior high school, my homeroom teacher took the lead in spreading the rumor that my mobile phone was stolen and slapped me in the face in class. The discrimination and cold violence from the whole class made me suffer from depression. When I asked for a deferral of the exam, the homeroom teacher called me melodramatic. After five years of treating my illness, my family's savings were completely exhausted, and my parents worked themselves to death. However, the homeroom teacher was honorably retired with the "Lifetime Excellent Teacher Award" just because he was a relative of the headmaster. I felt a sharp pain in my heart on the sickbed and died of a heart attack. When I woke up, I found myself reborn on the very day when he framed me for stealing the mobile phone.
