MKON-087 Meeting my old crush from school and the ending

When I was a student, I was bullied because I was falsely accused of being nosy. On the day I invited my first girlfriend Jun over to my house, the bully Okazawa happened to move in next door. He entered the house and made a mess, but Jun aggressively chased Okazawa away. However, Jun was later offended by Okazawa, and was forced into his room by him on the way home. Jun, who saved me from the worst life, was taken into the hands of DQN and shot in the vagina.
