Are Lee Seung Gi and Yoona still dating?

To say the conclusion first, Lee Seung Gi and Girls' Generation's Yoona are still dating well. As I mentioned through this article, Seung Gi is trying to protect his girlfriend, refrain from commenting about her in public. Lee Seung Gi's new film 'Today's Love' was released in January 2015, and he was interviewed by various Korean media outlets. Of course, the writers asked about his girlfriend, but he said, "She's doing fine, but my partner in the movie is actress Moon Chae Won, and I think I have to talk about the actress." Actually, Seung Gi and Yoona are regarded as two of the most good-natured entertainers among people in the world of kpop. It is very likely that the two will be long time lovers.(However, it's sad that Seung Gi has to go into the army in the next few years.

2PM's Nichkhun and Girls' Generation's Tiffany are still having special relationship too. The two have admitted to being in a romantic relationship with each other in April 2014, stating, "We have been good friends for years and recently became lovers." Well, however, Nichkhun and Tiffany started to date much earlier than that. It has been about 6 years since the two idol stars' special relationship had begun. And the two have similar personalities. They laugh a lot and are good-tempered. When I visited Hong Kong to watch MAMA 2014, the two looked just great.

Girls' Generation's Taeyeon and EXO's Baekhyun are dating well, so far. It has been only a year since the two started to date, and it seems that they didn't fall out of love yet. However, I think Taeyeon & Baekhyun is the most risky couple among the 3 top idol couples. Why? 
Baekhyun is too young. Baekhyun, the young idol star, is so popular among other young pretty females, while Taeyeon is 3 years older than him. It seems that Taeyeon has to do something special to maintain the relationship, but she is not so sociable as she looks.
