This is the case Kodama Yuhei . This case is too sad and "breakheart" of many peoples , a death because bullying in school . I'm from Vietnam , I also know this case . Rest in peace , Yuhei sempai . If the human have next life ( afterlife ) , I believe Yuhei has a happy life and all the best . In this world , the life is very harsh and complex , it's not peaceful like exterior . Not easy have happy , with many peoples .
