Lyrics from The Hardest Thing by Joaftheloaf and Feather.

Walking up to you

Is the hardest thing to do

And every time I look into your eyes

I forget just what to do

Fitz caressed the cheek Simmons pecked. She had never kissed him before, in any way. He could feel his cheeks burning up and he clutched the pillow tighter. Lying down on his bed, he started to recall their first day in SHIELD…

Deciding what to say

Tryin' to chase my fears away

But every time I look into your eyes

Nerves begin to fray

"Now, behave, the two of you. I don't want my lab to explode. Don't think I've never heard of the two of you blowing up the university lab." Simmons smiled while Fitz looked at her. They had been the best of friends since high school, and the first year out of college both of them were recruited into SHIELD. Never in his entire life would he have thought that he would be part of a secret division.

All this time spent down, for my life to turn around

I know I'll find a way, to be with you someday

And someday you'll see, you'll notice me

"Leo! Can you just look at the equipment? Oh, I'm in love!" She squealed with delight. He had this flying feeling when she said it; he had never admitted to his life-long partner that he had the biggest crush on her, and he never did so because he was too shy. He was afraid that she would let out another one of her hearty laughs and say, "Fitz, we're best friends, not lovers. We'll never be lovers."

All the times I've tried

To be right by your side

But the hardest thing of all to do

Is to try and talk with you

"Looks like it's you and me from now on." Simmons said, placing down the last piece of luggage they had. "Well it's not Beverly Hills, but it's a home." Fitz said. He didn't mean an actual home though. He is home where Simmons is. He didn't know where the thought come from, but he remembered hearing someone say, "Home is where the heart is", and he had definitely found his. It was right here, right next beside him.

Wishing from afar

Tryin' to find the right star

But the hardest thing of all to do

Is to try and talk with you

"Shooting star!" Yelled Fitz. The two best friends sat by the window. "I wish I - no, we – will be famous scientists. The world will know our names and…" Fitz was too distracted to listen to Simmons' prayer. He was weaving up his own. He was wishing, very hard, that one day Simmons would notice his affection for her without him saying it out loud. They both finished their prayers and stood up.

"Jemma?"

"Yeah?"

"Uh… nothing. Never mind." Oh, no. There it goes again.

A smile appeared on her lips. "Goodnight, Fitz." She said, petting his curly hair.

How am I gonna act?

What will I do?

When I'm finally with you

How will time pass us by?

Stay by my side

I don't know what to do

I hope that you feel the same way I do

I hope you do

Snapping back to present day, Fitz opened his eyes from his dream-like state. Those memories were his favorite from his little collection of moments with his partner. Sitting up, he sagged his shoulders. No, this will not continue. She's just his friend, why would it be hard to tell her just three simple words? He was on the verge of losing her, for God's sake! And he couldn't even manage three words? Three simple words?

Standing at your door

Not knowing what to do

I must be crazy for even saying this

But I'm in love with you

"Uh… Jemma? Can I talk to you for a second?" Fitz slipped into the lab uneasily, tugging at his clothes. "Yes?" Simmons was concentrated on one of her mice, carefully ejecting a vaccine into the white rodent. "Look, I've always had this problem with expressing myself and I'm socially awkward and stuff but… But here it is." Fitz paused and gulped. "I… I love you."

I look into your eyes

What a perfect surprise

You're not crazy for saying this

Cause I love you too

"You what?"

"There. I've said it."

"Fitz, you silly-" She didn't finish her sentence. Running towards the specialist, she pressed her lips into his, her arms thrown over his shoulders. Fitz returned the kiss, his hands snaking to her back. They stayed glued to each other for a moment and finally parted when Skye and Ward came into the lab. Fitz and Simmons blushed while Skye bit her lip, nudging Ward with her elbow. Ward sighed and rolled his eyes, reaching into his pocket to grab a five-dollar bill. "I win." Skye said teasingly, waving the bill in front of him. Fitz and Simmons looked at each other and giggled.

All this time spent down, for my life to turn around

I think l found a way, to be with you someday

And today you've seen, you've noticed me
