I'm guessing pilgyun is in his early 20's since he's already graduated school and dad is probably in his 40's mayyybe late 30's but that's just a guess. Hopefully when this is over the author will do a Q&A.
My head cannon is that its around a 12 years age gap, I'm guessing pilgyun is around 22-24 while is around 34-36 IM JUST GUESSING (or rather, I may or may not have etched it in my head without realising-)
ohhh thanks a bunch guys, it's also been in my mind lately, (￣∇￣")
can anyone tell me the age gap between this two? i mean nanmu & pilgyun? how old is nanmu also pil?!
