What does it mean?

Frozen in place I stood there staring at the couple, my heart raced and I could feel my vision getting blurry. 

"What's wrong?"

Luke asked with worry but I paid him no heed as I was too focused on Lione right now. Suddenly the bitter sinking feeling in my gut turned to anger without warning I got up from my seat, the action causing my chair to scrape against the floor making a loud screeching noise. 

All eyes turned on me including Lione and his girlfriend. Noticing me he raised a brow in question. Not wasting any time I turned around and left leaving Luke to scramble after me. 

Stomping my way to the parking lot I swung the door open, got inside the car and shut it with a bang. Taking his place in the driver seat Luke looked at me in confusion.

"You okay? What happened back there?"

"Nothing"

I answered not looking at him. 

"Sure didn't look like nothing"

He persisted and I sighed closing my eyes then turned to him.
