- at the beggining, when taeyeon is in the train station, you can see a sign that says "stop on red signal" ( (at 0:31), but the ligths are giving mixed signals as it continues to change between green and red, representing how Taeyeon wants to stop the relationship but can't control herself, so she comes back to him everytime
- the book on her room is Only Time Will Tell by Jeffrey Archer, don't think the plot has much to do with the MV but the title might represent the open ending, since we don't know if she ends up breaking up with him or not
this quote from the book does seem to represent her situation pretty well tho
- The wounds she has on her body are due to the roses thrown by the audience. You can see in this scene how a rose make a scracth on her nose.
did you notice anything else?
