I am doing age calculations and I think they have 10-12 age difference. Now if we see MC as a child he looked around 9-10. Since he is in high school first year and he was adopted 5-6 years ago that makes sense. Now when it comes to ML age, when Mc was 9-10 and that incident happen he was just out of military so he was around 21-22 age since korean men get in college around when they are 19-20 and they spend 1 and half year in military so that age makes sense. Now when it comes to detective he was around 25-26 maybe more when incident happen because he was newby in detective thing. I might be wrong but these are all my assumptions.
