Honestly, if N's consistent declarations for Seohyun continues, I wouldn't be surprised if someone introduces them or sets them up on a blind date later in the future (of course, if they're still single).
People have been calling N a 소나무 (Pine Tree haha!) in Korea because he's been so firm in repeating "Seohyun" for over two years now.

It's time for VIXX to draw their ideal types, when N showed his direct love answer.
Hongbin: Wow! That's very obvious! (Pointing to the writing underneath N's drawing).
N: No, no! That's the trendy phrase these days. I didn't target a specific person.
Ravi: Did you receive chocolate Seo-hyun? (Note: On the internet, people put the word Seo-hyun on the end of statements that end with "ssuh-yoh,"replacing "ssuh-yoh" with "seo-hyun" because they sound alike, and it's just a internet slang).
N: No~ It's the trendy phrase these days.
Ravi: Do you like SNSD's Seohyun Sunbaenim?
N: I like her~ =^^=

I am Rovix. Today while waiting for Music Core, the fact that N personally taught MC Seo how to dance to the Mummy dance is no secret. Also, the fact that N jumped up and down because he was happy is not a secret either.

Notice at 1:34 a staff hands the mic to Seohyun, and you see N look at Seohyun. I would assume this is when N first started taking interest in her after meeting her backstage (reference: My Idol video above)
Seohyun
I wonder if this list will grow....
May 2013 Issue of High Cut Magazine
High Cut: Who is a junior girl (or boy) group that you’ve been paying close attention to the most lately?
Seohyun: There are a lot of talented juniors these days. Out of them, the groups that left the strongest impressions with their performances and concepts on stage are VIXX and B.A.P.
