oh god stop saying he's ur daughter in law. i just want the story to reveal that he doesnt really have a son so i wont be creeped out anymore and wth?!!! idk if i just forgot about it but HE HAS A FREAKING WIFE AND HE JUST K WORD HER LIKE THAT?!!!
Check chapter 3 page 12. His wife was pregnant with the baby before they got married, it's not his son technically. In the old time they get married kinda early so I think he's in his 30s at most. Lets just say that his son is 18, the ML got married at 18 so maybe 36?
this is such a cute and educational manhwa :(( so sad it ended
