Eh? I thought he was always like the सेकंड most लोकप्रिय after Hyun joong 0-0 I have seen टिप्पणियाँ all commenting about how cool and cute kyu jong is lol. but i think one of the reasons why he isnt as लोकप्रिय is because he can be quite quiet... and he doesnt get as hyper as the other members. i guess आप can say its that. He's really mature.
Mmm... maybe it's not because people don't like him, but he's not as atractive as the other. Kyu Jong is calm and nice. Maybe he needs to play in और film या sing in film soundtracks. But don't worry, when people प्यार SS501, it means they प्यार him too.^^
emm i dont think so . mayb just for some of the people thought like tht . coz for me, i प्यार kyu jong n i pay attntion to KKJ और that other members . n to answer ur question, i think bcoz of his attitude where he prefers to be a humble man; i mean not like other members who like to talk much . या mayb other mmbers are और like knowing how to get ppl attntion compared to him . he just a kind man .
