Not stopping after UN disbanded, Kim Jeong-hoon also recorded solo songs and has released several albums. UN, also known as United N-Generation, released 5 albums between 2000 to 2005. The duo initially debuted in 1999, but it wasn’t until June 2000 that they made their first album public.

In an interview with International bnt, he shared insight into the reason for their disbandment. He said that it was because they were both busy with their respective solo careers, so a reunion probably isn’t in their plans.

There were rumors going around about their disbandment, including that they had a bad relationship, but Choi Jung-won said, “We didn’t really fight. There can be collisions when you are together. We didn’t talk for a short while, but then we resolved things.” Kim Jeon-hoon also responded to this by saying “There had been a lot of talk going on about how we disbanded because of our conflicting schedules. However, that wasn’t the reason. It was merely due to our contracts expiring.”

Here is a list of both Kim Jeong-hoon’s solo and duo songs.

Thoughts on Dating and Marriage

Currently, Kim Jeong-hoon is reported single. There are no current rumors about him having a girlfriend, either. But, there was a rumor in the past suggesting that he might have dated Yoon Eun-hye. Whether it was true or not at any point in time is still not clear since neither of them has spoken about the matter to this day.

But, he once admitted that he was in a relationship before. When he was asked about marriage plans and dating, he answered, “I don’t think it’s time yet since I haven’t matured. When I was in my early 20’s, I did date someone who was 10 years younger than me, as well as being in a relationship with a foreigner.”
