My Youth Love Story Indeed Has a Substitute

My name is Hikigaya Hachiman. I am 18 years old. I live in XX District, Chiba Prefecture. I am unmarried and have a younger sister. I am a senior in Sobu High School. I go home alone after club activities every day. I drink at least one can of MAX coffee every day and then do negative thinking for 20 minutes to completely empty my brain. I must go to bed before 11 o'clock in the evening and make sure I get 8 hours of sleep. I can basically sleep soundly until dawn, like a baby, leaving no fatigue and stress. When I was a child, I suddenly awakened as a substitute, and unexpectedly met Jotaro when I was 14 years old, and we embarked on that 50-day trip together. After defeating Dio, I said goodbye to Jotaro and others and returned to my own life. However, what I didn't expect was that the way I met them again would be so fresh and refined.
