Blazing Summer

When the whole internet was going crazy, she slapped everyone in the face with her strength. When she finally mustered up the courage to propose to her boyfriend of six years, an accident took her life away. When he woke up, he found that he was reborn as his original student, still in the third year after his death. What was originally thought to be an accidental death turned into a premeditated murder. The boyfriend who had a good relationship turned into a scumbag who killed a thousand people, and was inextricably linked to his own death. The male protagonist is someone else.
