The group only released debut album 15 to 30 in April 2002 and the members separated one year later to follow their own paths .
Shinvi was promoted by SM Entertainment but was actually under a subsidiary of the company, similarly to their labelmate group Milk.
Shinhwa member Jun Jin appeared in the music video of their title song, "To My Friend".
"Darling" was voted as the next song for the group to promote, and it was also used in the online game Shining Lore.
Though Yuna appeared in the music video for "My Angel My Light", only Soo Jin and Sang Eun were featured on the album's jacket.
