September 7 marks the 21st debut anniversary of K-Pop's legendary 1st-generation idol group, H.O.T!
Former H.O.T main vocalist Kangta took to his Instagram to commemorate the occasion, referring to his old group as the idol industry's trilobite (fossils of one of the oldest living creatures on earth)! Sure, H.O.T are an old, legendary group, but are they trilobite old? Kangta's full post read, "21st anniversary! Congratulations, everyone hehe. I would like to thank everyone who has been with us for the last 21 years. #H.O.T #TheIdolIndustry's #Trilobite."
