Only One is the third album by South Korean boyband Shinhwa, released on May 27, 2000. The album was delayed three months to give SM Entertainment's new group at the time, Fly to the Sky a chance to debut. The album's title song was released as the album's lead single, with "All Your Dreams", "First Love", and "Wedding March (Your Side)" being subsequent singles. Only One sold 423,873 copies and reached number one on the Recording Industry Association Korea music chart.

Information is adapted from the liner notes of Only One:

In the music video, "Only One", the members can be seen dancing in a warehouse or in a dark place. They also wore various clothings, from a black suit to wearing grey pants only. In the music video, "All Your Dreams", in which Jun Jin stars as the main lead, the members of Shinhwa play various role. It also featured another SM Entertainment group, Black Beat as well as Kim Bomi. The music video tells the story of a man (Jun Jin) and a woman (Kim Bomi) who is giving off the image of being attracted to each other romantically. However, another man (play by a member from Black Beat) also show the same love interest in the woman as well, thus initiating a fight between Shinhwa and Black Beat towards the end of the music video. "First Love", unlike the other two, did not show Shinhwa dancing in a choreographed dance nor portray a story. It features instead various clips of Shinhwa, from practicing their dancing to having their concerts. "Wedding March", again starring Jun Jin as the main role, shows a man proposing to his love interest.
