Jace's POV

I walked down the aisle pushing the shopping cart with me.

Clary was beside me reading off the grocery list her mom, Jocelyn, gave her. "Milk, eggs, yogurt..." She said.

She grabbed the stuff.

We got some more stuff.

About 10 minutes later, we only had one item left.

"I'll get it," Clary volunteered and hurried off to get it.

I stood next to the cart and waited for her.

I saw a girl stare at me. She approached me. She had blond hair with some red highlights and the deepest blue eyes I had ever seen.

"Hi," She said. She seemed shy.

"Hi," I said back. I didn't have much interest in her. She wasn't as beautiful as Clary.

I didn't expect her to do anything. She stood there for a few seconds, then lunged at me.

She started kissing me.

Her lips tasted horrible. They were sour and bitter put together to make one horrible taste.

I was going to fight back when a searing pain went through my head. It hurt.

When the pain had subsided a little, I still had a horrible headache.

I tried to push the girl off of me, but my head hurt so bad.

When she finally stopped for air, I jumped back. My head hurt really bad.

I clutched my head. I looked up and I saw Clary running out of the store.

Clary's POV

I was walking back from getting the last item, when I saw Jace kissing a blonde haired girl.

I gasped and tears sprang into my eyes. Just when I thought we had overcome everything! I thought.

I threw the item I was holding and ran out of the store, tears streaming down my face.

Jace's POV

I ran after Clary.

I had ditched the blonde haired girl.

I ran after her, but my headache caused me to run slower than usual.

When I almost caught up to her, I suddenly felt a searing pain n my stomach.

It hurt so bad that I fell to my knees.

I looked at Clary, who had turned back to look at me.

She looked and then continued walking.

My heart sank.

Clary's POV

I ran as fast as I could.

I suddenly heard a thump behind me.

Jace was on his knees.

I kept running. He was probably faking. Jace never trips.

I ran home, still crying.

My mother greeted me at the door. "Did you- Wait! Why are you crying? What happened?" she asked.

"J- Jace c- cheated on me!" I sobbed.

Then, suddenly, my mom got a look of pure anger on her face.

Jace's POV

I wanted to chase after Clary some more, but the pain was unbearable, so I came home to the Institute, which was closer.

Thankfully, no one was home when I got there. I didn't want anyone to see me like this.

I walked slowly to my room.

When I got there, I lied down on my bed.

My head and stomach throbbed. I finally went to sleep to get rid of the pain.

Thankfully, the pain was gone when I woke up, but I had horrible nightmares instead.
