Music Video

The beginning of the music video has the members dancing into the night. Though every once in a while it switches over to show each individual member in different white rooms. From catching a butterfly in a glass container, having different reflection in mirrors, lighting up candles with a touch of a finger, and turning back time; it shows that the members do have a darker side to them. During the second verse the members are dancing on water with a black car behind them. The members do sit in that same exact car later on. Towards the end of the video the members are shown to have black wings coming out of their backs. The music video ends with the members looking at the city from a ledge either sitting or standing.

The music video has over 28 million views.
