So many options came to my mind. As for majority, people chose Jay, but there were a lot happen between Key-Cole and Jin-Cole (2AM's Jinwoon), so I also keep in mind these couples.
From Idol show with Suju, I love the chemistry between her and Sungmin...and in SGB, i love how Siwon keep staring at her endlessly and there was time i thought she tried to avoid his stare when explain the question to him. Donghae also showed his affection in Nicole during their guessing in SGB as well, and there was one time when Suju and Kara guessed together, he was so much in love with teasing her which made me shift to this couple as well.
What's else? There are Minhwan of FT Island as well eventhough he's younger than her 1 year. I love their interatcion at idol show when Kara was the host and FT island was guesses. In my point of view, it seems like Minhwan really interested in her. And also in a radio show, Jaejin and Minhwan both asked Nicole supported them for their solo singing. The way Minhwan stared at her...i just love it too much. During this radio show, I saw FT island's Jonghyun showed his concern to her as well and teasing her....<3.
Aigoo, what's else? my hand is tired because of typing already. Ah, 2PM, Junsu as in Idol show 3. They made a cute couple. Junsu was shy when he stepped out for her. We can see that quite clearly since other member supported him gave him courage. Jay was very charming and cool during SGB's level with me section which made him became one of my option.
Shinee. There are 3 members: Key, Minho and Jonghyun. As for Jonghyun, he had gf already, but there was one time when Nicole participated in Dream girl's battle and Shinee present as guesses. When the MC asked her and the other girl from SNSD dance in front of Shinee, i saw how Jonghyun stared at her, of course, this can't help since she was so cute at that moment. As for Key, he is already her close friend and they showed their affection as well, he is an obvious option for almost her fans. As for Minho, if everyone what Dream Team will see how Minho treat her and i believe everyone would shift to this couple as well.
There are DBSK and SS501. But I'm so so tired already. Recently, she became the manager for "FC men", I'm expecting more interesting news from now on since the issue between Kara and DSP was solved
