Omg I love the PV <3.
This is my interpretation (I'm just saying what I got out of the PV, I don't know what's right or wrong):
The lyrics seem to speak a lot about ambivalence and emotional conflict. She's speaking of someone she loves, yet can't stand sometimes. Even the song is a contrast between two different emotions since it goes back and forth between rock and ballad-y.
Therefore we get conflicting views of similar people. The two girls are skipping one moment, next they're not. The woman in the navy (?) uniform is acting all responsible one moment, then ripping her uniform off the next. Even that creepy mime guy, if you looked at his mouth, one side was smiling and one was frowning. All are showing ambivalent feelings.
This is just what I got out of it though
