You looked very happy today.
I soon found out you had broken with him.
I am very happy that you dont have to go through that anymore.

I left only a small note today.
It simply said "I'm proud of you
~KS"

This time i got to see you read it.
A smile spread across your face.
Although you did something different this time.
You didn't fold it and put it away.
You wrote something on the back and closed your locker, putting it back in with a little bit poking out.

As soon as i knew you wouldn't find me near your locker, i walked over to it quickly grabbing the note and walking back to my own.

"To KS (whoever you might be),
I would love to meet you and know who you really are. Thank you for all those little notes. I hope we can meet soon.
~Namjoon"

I smiled and held the note to my chest.
I quickly grabbed another piece of paper and wrote a reply.

"Dear Namjoon,
As much as it pains me, I can not meet you yet. Although I'll give you a clue as to who i am. We are in a few classes together and you know me. Sorry if this doesn't help. See you around.
~KS"

The real clue was not quite the class thing but more so the 'see you around'.
I doubt he would have realised that.
