Translator’s Note: The article talks about how the fandom works. I only pinpoint the statements about JYJ.
There’s an article in Nate that says JYJ has 40 year old and older fans. They interviewed one who is a lawyer but he used a pseudonym (Mr Lee) during the interview lol. He went to the JYJ expo and attended the fanmeet.
“I like JYJ but I am not one of those sasaeng fans that go in front of their houses.”
The article also stated that JYJ has a lot of ahjumma and ahjussi fans that can be very instrumental in their success due to their position/occupation.
Mr Lee, married for 11 years this year: “I went to Thailand, one of the countries where they held their world tour, and watch the JYJ concert with my kids. Watching them lessens my stress”
