What if minjin is the box head dude's son (⊙…⊙ )

maybe. I dont remember if they ever mention the professor age but i assumed he was in his late 20s to early 30s, and im guessing Minjin is in his late teens. so they would have between a 10 to 15 year old age gap. thats why i didnt think box head was his father. but as i said i dont remember if they ever mention their ages. and he could have had him at like 15-17 but honeslty i dont think box head was getting any when he was in high school. he seemed very antisocial from the flashbacks, but ya never know.

I believe the professor is 27. ( I can be thinking of another character though), and I don’t think they’ve given Minjin’s actual age, but he’s a minor, so that makes him under 20. In order for his to be a 27 year old son’s, At the youngest Minjin would have to be 15 (15+12=27), but I doubt he’s 15 or his dad (whoever he may be) was 12 when he conceived him.
If Italian people really have that saying then they are wilding when it comes to relationships (⊙…⊙ )
