I see everyone is freaking out about the age of the MC, he is NOT 15 okay. It said OVER 10 years ago when the MC was 5 and his uncle was the same age the MC is now, in chapter 6 the mc said he just turned 20 so the uncle was 20 years old back then and the MC was 5. The flashback in the early chapter was 15 years ago not 10 but it did say that it was over 10 years ago.
