Why is my heart beating so fast

Gui pov
I walked to lunch and I saw Aaron with a girl
maybe that's why he's pretending not to know me- I thought
I walked up to the table and sat next to Wang Zi and Xio Xun
hey- I said smiling
HEY- they both said
Aaron looked at me and i forced a smile

Hi I'm Hebe Aaron's Fiancee- Hebe said
Gui Gui's Expression changed

I'm going to the library- I said
I ran home instead he has a fiancee - I cried I layed in my bed and cried myself to sleep
I must have been asleep for a really long time because when I woke up I heard a knock I opened the door and Xio Xun hugged me
why did you leave school we were so worried about you- Xio Xun said
Oh I was feeeling sick- I said
Wang Zi and Xio Xun came in and then I saw Aaron and Hebe also come in
