"I still can't believe I'm at senior prom with Grant Gustin!!"

He scrunches up his face in a very perplexed  expression as he stares at the redhead seated across from him at the table. Clearly confused by her outburst.

"Um, why? I'm just a guy, no one special.  Plus, Sarah you asked me, remember."

Sarah giggles as she picks up her glass of soda, arching her eyebrow at the green eyed boy sitting across from her.

"Oh honey, you aren't just a boy. You're fine as fuck! And I'm surprised myself that you said yes. I thought for sure you would have been going with..."

She watches as his eyes drift from her to checking out a pretty girl in a pale pink dress across the room.  Her curly brown hair artfully pulled back with sparkling flower shaped clips.  Sarah rolls her eyes as she notices her prom date smile to himself as he watches that girl sitting by herself, toying with the corsage on her wrist.

"Grant..."

He hums softly in reply but still doesn't look back her way.   She huffs slightly in disappointment and tries again.

"Grant????"

His voice is soft as he answers, but his eyes still don't quite focus back on her.

"What's up Sarah?  What were you saying?  Who did you think I would have rather come with??"

Sarah sets her drink back down on the table and reaches across to grab one of his hands.  He finally fully looks back at her, his green eyes meeting her pale blue ones.

"Grant, you are so adorably clueless.  I know you would rather be here with Kate.  I've seen how you two look at each other when no one is paying attention.  So thank you for being noble and accepting my offer.  But honestly....   make a move hun.  Like really."

With that she lets go of his hand and pushes back from the table, standing up and starting to walk away.

He scrunches up his nose again as his hand reaches out to wrap around her wrist before she moves too far away.

"Wait!  Where are you going??"

Sarah smiles sweetly as she detaches his hand from her wrist.

"Don't worry babe, I'll be back. Heading to touch up my makeup. But be good Grant, follow your heart. Okay?"

He nods slowly as he watches her walk away. Leaving him to sit there alone with his thoughts, in a ballroom full of people. Music thumping around him.

Is what she saying true?

Would he rather be here with Katie?

A quick glance back across the room finds big brown eyes staring back at him. Katie tilts her head to the side and gives him a small, confused smile. Probably wondering why he is sitting by himself. Why Sarah walked away.

Grant averts his eyes, unable to stop to blush that crawls up his cheeks.

She is his, has been since they were young. Since they got married, with the help of Mr Bunny, in the back yard wearing their Easter best. Six year old Tommy pledging his forever love to five and a half year old Katie.

Grant finds his feet bringing him across the room as an old N Sync song begins to play. Drawing couples to the dance floor.

No one but he and Katie know that they had their first test kisses to this in her basement when they were both just shy of 10 years old. That party sophomore year, Mike Walker's party, and their epic mishap at suck-n-blow that caused the makeout session, THAT was the first time they kissed in front of other people though.

I'll be your strength
I'll give you hope
Keeping your faith when it's gone
The one you should call
Was standing there all along

Finally he is standing in front of her, although she is looking down now. Fingernails painted the same pale pink as her dress pick at the table cloth in front of her.

"Katie my love..."

She smiles when she looks up at him, eyes sparkling as she sees her best friend.  And suddenly Grant feels light as air.  Her voice is soft, breathy.

"Hi Tommy.  Shouldn't you be dancing with Sarah??"

He shakes his head as he extends a hand to her, helping her to her feet.

"No Darling, this is OUR song.  I wanted to dance with you."

The blush on her cheeks as he leads her on to the dance floor is honestly one of the cutest things he has ever seen in all of his 18 years.  And the feeling of her in his arms....

Nothing else can compare to that.

Her head is rested on his shoulder as she whispers softly in his ear.

"Tommy, you're my best friend.  For always."

His heart beats rapidly in his chest and he knows it is more than that.  That Katie's words mean more than that.

That as they sway back and forth, they are alone on their own bubble in a room full of people.

And this is what it means to follow his heart.

"You're mine too.  I'll love you forever Katie, I promise."

Every word I say is true
This I promise you
Ooh, I promise you
