Since your parents passed dead, you had to drop out of school to raise your younger brother-Mascor, who is 6 years younger than you

When he was 18 years old. The building where you live experiences an earthquake. Because of protecting Mascor, you suffered a brain injury and your mind became stupid

He gradually couldn't stand your stupid brain

Today you accidentally broke a glass, Mascor angrily pushed you out of the pile of broken glass

"How long are you going to bother me?!You crazy!!"
