Aside for DBSK/TVXQ, SuJu and, this year, Big Bang, not many idol groups can claim to have been together for a decade and more. (Big Bang are like the only idol group that I can remember having the same lineup for 10 years.)
SHINHWA are the only one who have been together for nearly 20 years. They have been dubbed the best idols in the variety world and extremely talented individuals. They even have their own companies. (for example, Andy’s company are responsible for the existence of Teen Top) The best thing is that when their contract expired the first time, their original company only wanted to resign Eric. They left the company together, had to pay a ton of money to keep their name and pursued their careers together.
SHINHWA ❤ the legendary kings and idols.
P.S.: Not trying to cause Fan World War III, but this is something you should all know. Many new kpop fans are only stanning their faves, but have -1% knowledge of K-Pop amazing history.
P.S.S.: Also, respect the senior groups. If it was not for them and their hard work, I doubt kpop would have been just as great. Hell, none of the new groups would be where they are today. For groups to be doing well in Japan, the pioneers like Super Junior, DBSK/TVXQ, BoA, KARA (disbanded), Supernova (and also K-Rock bands like FTIsland and CNBlue) had to go head to head with Japanese artists.
