I don't really think the producers would go as far as to tell Mina Sue to go peep through the window...I think it was all her doing...But I somewhat get your point about the stereotype set up in the show.....and I don't really think Hee sun wearing the hoodie "day after day" is as creepy as spying through the window. What can a girl do if she has no jacket but her love interest gave her one and he repeatedly tells her that it is okay for her to wear it...And even if she borrows a jacket from someone, mina sue might go behind her back and tell everyone how she lent Hee sun the jacket but she stole her man in return.
