To me, this the quintessential Korean romantic drama. The story, acting, and the use of music are outstanding and just some of the reasons to recommend ths film. It really evokes emotions and you'll likely cry at times.
She is an impressive actress, and my favorite Korean access for over 20 years. Her ability to excel in comedic scenes and dramatic scenes is impressive. It's hard to shine in both, but she does. She gets my vote.
