Just tell him that I <3 his band and him. Then ask him for his autograph and picture. (Trying to act calm but inside I'm screaming!!) Also ask him to say hi to everyone in SHINee later.
First I would apologize for bumping into him and then I would strick up a conversation with him and after a while ask for if I could take a picture with him
I be like *gasp* shinee! and he be like u like shinee? and i be like psh its my life in english cuz we probably will bump in America cuz I cant go to Korea LOL ok
So I will get dem selfiess and shares it to shinee pages and be like this is real, r u ppl jelly
