This is a story that just popped in my head. It takes place after 5x10, it's a Delena and OC story. After breaking up with Elena, Damon runs off for 10 months and no one knows where to. So while he was gone Elena met a new guy on campus named Daniel and after 7 months of dating, he proposed and she said yes. Now let's see how Damon reacts to the news when he returns to win Elena back.

Damon's POV:

I had to come back. I missed her too much. She probably hates me now for leaving her like that but I needed to do it. We both needed to move on and see what life was like without one another. She's my best friend, the love of my life, hell she is my life. These past 10 months have been hell without her, I wasn't myself when we were apart. I did awful things, disgusting things. I just need her. HER.

Elena at college:

(In Elena's voice)

Dear Diary,

It's such a nice day out. Maybe Daniel and I could have a picnic. Oh Daniel yeah I forgot to mention to you earlier, I'm engaged, he's my fiancé. Gosh I still haven't gotten used to saying that yet. He proposed to me about a month ago on a beautiful little beach right outside of town. That was the greatest moment of my life, even though we both know I'm immortal. Yes, Daniel knows I'm a vampire. Actually, so is he. Odd coincidence huh? God I really do love him. I cannot wait to spend eternity with him. And an extra bonus is that everyone that I love loves him, not as much as me of course. Lol. On a different note no one still has heard from Damon. I'm still worried, I mean we may not be together anymore, nor will we ever but I'm still concerned. Daniel is so much different than Damon, Daniel is ok with me being worried and not jealous like Damon. He understands that no matter what's happened in the past I still love and care about him. In love though, absolutely not. That's just who I am. However, I hate him too. How dare he just leave me like that and run away. He hasn't even reached out to Stefan. Typical.

-Elena's phone begins to ring, Daniels picture appears

Elena-

Funny, I was just thinking about you

Daniel-

Oh yeah? What about me?

Elena-

Just how much I love you and how I could have gotten so lucky

Daniel-

I ask myself the same thing everyday

Elena-

Hmm

Daniel-

So where are you? I just stopped by the dorm and Care said you went out

Elena-

Oh, I just needed a quiet place to write, all Caroline is doing right now is planning the wedding

Daniel-

You know, I'm beginning to think she's more invested in our wedding then both of us combined

Elena-

Well, you know Caroline, I tried telling her that we wanted to wait since we literally have all of eternity to get married but she won't listen to me as usual

Daniel-

Hmm. So do you want to meet up now or do you still need to write?

Elena-

Actually I was about to call you because I wanted to head to Mystic Falls for a few hours, I want to see Stefan and Jer

Daniel-

Do you want me to come with you?

Elena-

Of course I do. You are my fiancé after all, and they would probably snap my neck if I don't bring you

Daniel-

Good point. Meet by your car in 2 minutes?

Elena-

I'm already there

-Suddenly he comes up behind her

Daniel-

So am I

-They hang up, he spins Elena around and kisses her

Elena-

Ok, let's go

-They hop in the car and drive off. After a couple of hours of driving on endless highways they arrived at the Salvatore mansion

-When they pull up they hear faint yelling coming from inside, Elena zooms in

***Enter Elena***

Elena- Stefan?

-Stefan turns to Elena

Stefan- Elena. Um…

-Suddenly Damon walks in with a glass of liquor and a huge grin on his face once he notices Elena

-Elena in a whispered voice says…

Elena- Damon?

Damon- Hi!

-Then Daniel comes in, Damon looks confused, Elena swallows hard and throw her ring into her pocket

Daniel- Hey babe is everything…

-Everyone is silent

Damon- Who the hell are you?

Daniel-I'm Daniel,

-Elena cuts him off and grabs her ring from her pocket and puts it back on then places her left hand on Daniels chest to reveal the ring

Elena- My fiancé…
