Izaya x reader ONE SHOTS!

Izaya x Cheater reader

So im reading and scrolling through books. And i never seem to find any one shots like these. It's always the cannon character and  not the reader. Well ive made something just to piss u off.

I was strolling by getting Y/n something for her birthday. She was acting pretty jumpy latley and her birthday  was comimg up.
If i thought any better Od say she was pretty suspicious.
I didnt let it get to me, I was too involved in my work.
Y/n comes over.

"Whattsup Y/n"
"Nothing Izaya, how about you love?"
"Nothing much, I got you a little something for your birthday"
"Thats so sweet"
She looks at the bag but then her phone vibrates. She sees the text and is now in a rush to leave.
"Ive gotta go, seeya love" she pecks my cheeck and scatters off.
She left her phone.

I looked at who messaged her.
It was a man put down in her contacts as "Best friend".
I scroll through the messages and couldnt beleive what I was seeing.
There were "love messages" and "lets meet up again ;)" messages.
I looked at when she started messaging this guy and how long she had his number. Well hlw ironkc she had for as long as we were dating.

"Izaya i think forgot my-"

She stares blanckly at me.

"I-I can explain"
"Get out"
"Izaya"
"GET OUT"

I throw her phone out the window as I see her in front of the building.

Your pov

I didnt ever really think it would happen like this.

I lay down on my couch and look at the gift Izaya gave me.

I looked inside the gift bag and it was a necklace with a pendant , inside the pendant was a picture of us when we werent dating.When we were still friends. When everything was ok
