How old are they? I don't remember reading that
( ̄∇ ̄")
I don't think is been revealed. My guess is that Namwoo is in his early 20s, considering his a Uni student.
Si-eon maybe 40? I used to think he was in his mid 30s but when Namwoo told him that he should feel lucky that he still hangs out w him knowing how old he is, idk, but that made me think that Si-eon is much, much older than him.

Who wouldn't want to assassin that bastard even more when he's taking care of a child the same age... Poor Teo
