Well without reading the lyrics I have 3 interpretations for ourselves that are a bit simillar:
1 - Ayu is having a normal day in her life. The PV focus in a terror theme. Ayu is surrounded by Ayu wannabes, people who want to take the place from ayu and who hate her. Ayu bashers. They do everything to destroy her image either by ripping posters, playing with her face, torturing her, etc. (Ayu has been getting bad comments from some people in the chinese media like Alan Tam so the PV would be quite like a reply for all the bashing she's been facing)
2 - It's almost the same but those people aren't bashers. They're in fact twisted fans! They love ayu SOOOOO much they want to be exactly like her. That love is so disturbed it turns into crazy passion. They follow her everywhere, they don't let her have a normal life. They can't distinguish the difference between love and hate (Remember John lennon? he was killed by a fan !

). The fact that made me think that is because they study Ayu they want to know everything about her. One guy kisses her poster with so much twisted passion, like he was her lover or something and like the poster was the real person.
3 - the same but they're all Papparazzi hahahaha
