"Dear Yoseob,

I know you are happy with that Emily girl from America and that's okay I guess, I just wanted to know if you remember that 2 years ago on this same day you asked me to be your girlfriend. I hope you actually remember...and secretly, well no so secretly, I wish that everything could go back to the way it was

Yours still,

Amy."

"Dear Amy,

I didn't even know people still left hand written notes on lockers like in the movies. I have bad news for you: the locker you entered the letter is no loger yoseob's. I don't know who he is but he's not longer the owner of the locker 345, is mine now. I asked around for an Amy who was the girlfriend of a so called Yoseob and a friend of mine actually knew who you were and he told me where locker was so this is why you are probably reading my letter right now. It feels so good to write a letter!. Well, I guess that´s all. Wrong locker. 

PD: If I you let me I'd like to give you a friendly advice, don't write to boys who are already in a relationship even if the boy is your ex. Like imagine how you would feel like if you were the girl he's dating right now and you found a letter like the one you left on his locker! It would feel bad right? Don't do to others what you wouldn't like they do to you. 

Yours truly (such a cool goodbye phrase), 

Park Chanyeol. (nice to meet you)"
