Imagine this:

A group of guys (in my head, it's GOT7) are outside, on the street, just hanging out and all of the sudden, a beautiful girl walks by. The song then begins and the guys all start to follow her, singing their feelings to her. They just watch her awe-struck as she walks, eats, sits on the bus, and shops. Occasionally, she will look around or behind her and the guys will hide so that she doesn't see them. Then, at the end of the video/song, the girl walks up to a police officer, points to them (saying that the boys have been following her all day) and, as the police officer comedically chases the boys, the girl flips her hair and walks away with a smirk.
