I chose Onew, well, maybe because I'm SHINee fangirl;] And Onew is my favourite. Onew was really sweet to her on last episode of Dream Team, when he gave her a flag I think that they look cute togheter. And there was some episode of Six Sense Quiz(or something like that - I don't remeber the title), where they also made an appearance. Well not so much interaction between them, but that's enough for me - being in one show. I hope to see more Onew-Seungyeon in the future!
Long post is long :B
