I think he might be in his forty’s by now tho...
It was just ten years so if he was 18 then , he would be in his early 20s now and our dude would be 18 somethin(￣∇￣")
Later 20s #－.－)oops
It's 2048 rn and he went back to 2008 so he would indeed be in his 50's
Ohhhhhhhhh(⊙…⊙ )
They might change it for plot sake but I havent read it so idk
So he can just search for him in the future??
