Ages?

Pretty sure he’s like 38. I remember seeing a comment says he’s 38

I think they are almost a decade apart, so Yiyoung should have completed his military service and be 26-ish.

Look at chapter 45 - he’s 38 and Yiyoung is 23

So 15 yr age gap? Cool I'm totally down with that and it helps with the story line. Thanks people!
