Realisation before Crush

How do you call the moment when you almost have crush on someone but then you realise you can't be together?

Frustrating Crush

I often read my friends' facebook status that said thing such, "I'm still single because I have crush on anime character." Everytime I read that kind of status I was like, "Duh." I've watched cartoons and been interested in some characters but I haven't had crush on any of them.

Then I read Girls of the Wild's and I have a crush on Li Mi Nam. He's a high school student and a boxer. 

This crush makes me frustrated because:
1. he's fictional
2. he's a comic character so it's not even possible to meet the actor in real life
3. he's not the main character so I can't see him often
4. I can't find many fanfictions which include Li Mi Nam (yes, I like fanfiction)

It's not that I want to date Mi Nam. It's just .... I can't even explain.

Anyway, if you like Korean manhwa and martial art, I suggest you to read Girls of the Wild's.

p.s. I don't know Korean so I don't know the proper transliteration of Mi Nam's name. Is it Li Mi Nam? Or Lee Mi Nam? Or else?
