Dear you,
My heart felt so heavy when I saw the sadness that filled your eyes earlier.
I want to talk to you so bad and explain my side to you. I can sense that you feel the same way, too.
I know there's a lot of questions running in your mind right now. I wanted so bad to say hi but all I can do is looked into your eyes and flash an awkward smile.
How to handle you? (i don't even know, myself)
I kinda feel guilty because the last time we chatted each other I was ... kinda sweet to you, too.
What possibly could go wrong, right? I know you want to talk to me earlier but you haven't utter a word yet, I stood up and left.
