the year of Sorry Sorry: 2008. the year they became known and were finally acknowledged by the Kpop industry. they were pretty popular during their U times but Sorry Sorry brought them to a whole new level. it brought them to not only be known throughout Korea but it expanded them to South East Asia and beyond. it was also the year where i learned about them and fell in love with them. ^^ and you could also say, it was the last year that all of them were together.
