Back to School, Teacher Begs Me to Tone It Down

This book is partially adapted from the author's personal experiences. [Rebirth + System + Academic Genius + Feel-Good + Lighthearted] Rebirth? Or arriving in another world... Or perhaps the mind drifting back to the year of greatest regret. In the years after Jiang Jun graduated from university, due to painful childhood experiences and social pressure—middle school bullying, parental misunderstanding, and the death of someone most important—he never smiled again, eventually developing bipolar disorder and relying on medication at home. During a New Year's visit to his grandmother's house, he was crushed by family scolding and walked to the rooftop... As Jiang Jun departed, he encountered a system that brought him back to middle school. From then on, his fate began to change. He started to alter everything, unwilling to return to the original trajectory... But is all this truly 'reality'? In my past life I was timid; in this life, I'll drive you crazy, hehe~
