I'm not sure but I think that because of the video I. E. The masks, numbers and uniforms I think that the meaning is somewhere along the lines of people being pressured into think what other people want them to. The masks meaning that their putting on a show and the numbers meaning that they've had their individuality has been taken away. Also I think that maybe the focus is on someone you trust not necessarily a love or a teacher but someone important breaking that trust and now they find it hard to belief in anything, not just love, because they felt so certain about that person.
