All clips were collected from here on RU-vid, except my Twice concert footage and my TVXQ image search. I tried to leave most of the watermarks in place to give credit. The music you hear at the beginning and end was some free music available in my editing program (Microsoft ClipChamp). Thanks to everyone whose content I used! Stan Polyphia.
