can someone explain the ending to me?does kim joo young start coaching again?
no she doesn't start coaching. At the ending scene we saw a new mathematics coordinator who helps students to get accept in university . From that scene they wanted to show that this is something that will never end means many more coordinator like joo young will come and destroy families and this is why they show the picture of coach Kim. I hope you understood it now, tho I'm bad at explaining but this is what I analysed.
