This is 100% inspired by a video that has gone viral on the Internet these days, about a father and his daughter lip-syncing to Maroon 5's Girls Like You.

Also, a huge thanks to amyscascadingtabs on Tumblr for the help with this!

"Daddy, music!"

Wrapped in her favorite bathrobe and a towel after her shower and comfortably tucked against her father's chest, little Ana Santiago Peralta points towards Jake's phone on the bathroom sink. He looks at her with a small smile, hesitation visible in his eyes – she's supposed to go to sleep soon. But he finally takes the device into his hand. One song won't hurt.

"Okay, one song," he agrees to her request.

His smile broadens and a wave of warmth takes over his heart when he unlocks his phone and the screen lights up. There shows a picture of the three of them with Amy, all dressed up in matching outfits during the last Halloween.

"What you do want to listen to?"

"Tayor Swit," the toddler answers right away. She doesn't need to think about it even just a little, bouncing with excitement into her father's arms. It makes Jake grin with pride.

"I wonder who raised you to have such good taste already." He kisses the top of her head, still smiling. The girl giggles as he goes through his favorite singer's playlist in search of a song to put on.

Bingpot! He finds just the right one.

Usually, it's her daughter's small steps rushing towards the entrance as soon as Ana hears the door opening that welcome Amy home – but not that evening.

This time, the room is weirdly empty when she steps inside the apartment after a long day at work. There's no sign of her husband nor the little girl around.

She frowns at first, confused as to where they might be, until she hears it – the slightly muffled sound of music coming from the bathroom. Some Taylor Swift song, she recognizes. Shake It Off, she can even put a name on it, even from afar – you do not marry Jake Peralta without being able to tell the artist's different most famous hits apart.

She's become used to him putting his playlist out loud around the house by now, after years of living together. Even more so ever since they've had a child. It seems that he has passed his taste in music to Ana.

Amy's not really surprised by the noise, then.

What startles her, however, is the unexpected – yet quite endearing – sight they offer her when she finally joins them after taking off her coat and laying her purse aside.

Indeed, it seems like she's walking into a father-daughter lovely bonding moment. The child is stuck inside Jake's embrace, their heads bumping into each other's while the two of them are lip-syncing in turns to the lyrics of the song.

They both seem very into their little game – her husband's gently moving the both of them around to the rhythm of the music, staring into the mirror. They're sharing a same half-serious, half-amused expression as they simultaneously (and silently) mimic the "mmh mmh" parts.

No wonder why they didn't hear her arrive.

Amy leans against the doorframe, biting on her lower lip not to burst into laughter while watching the pair. She can feel her heart getting warmer with each second passing by.

They're adorable, she can't help but think. A small beam comes lighting up her face.

It doesn't take long for Jake to spot her reflection in the mirror. He offers her a huge smile back when their eyes meet through the glass; soon, hers grows bigger, fonder too, waving at him.

Hi, babe, he manages to mouth between two lyrics. In his arms, Ana still follows the song – or at least does her best at trying. He puts his whole attention back on the little girl. He can feel her whole body shudder against his chest, giggling at the silliness of what they're doing.

It makes him pause to look at her, eyes shining in pure bliss.

She truly is the most precious thing he's ever laid his gaze on in his whole life.

(Her, and his wife, obviously.)

Quickly though, he joins in their little 'battle' again. He sneaks some glances at Amy from time to time; she's wearing the same look in her glowing eyes and a soft beam on her face.

"Mommy!" Ana eventually spots her too.

She catches her mother laughing from behind. It makes her laugh along with her, loudly, the sound resonating through the walls of the bathroom.

That is music to her parents' ears. Even better than any Taylor Swift song.

Jake puts her back down so that she can go and greet Amy. Their daughter doesn't waste any second to run into the woman's open arms and pull her into a tight hug after a day apart.

"You were having fun?" she asks. She draws a little away from her to better look at the toddler. She only nods in return, her smile still wide on her small features, showing her dimples.

(The same as her father's.)

Amy looks up, exchanging a knowing glance with her husband.

After that, it doesn't take too long before the excitement cools down from the child's body, replaced with tiredness as she lets out a little yawn.

"Let's get you to bed."

Her mother takes her back into her arms and the little family finally leaves the bathroom to join Ana's bedroom, where her parents tuck her to bed after changing her into her pajamas.

It's only when they turn her lights off and head towards the living room alone that Jake eventually gets to properly greet his wife. With his hands at her waist, he keeps her close to his chest and gently pecks her lips. He then buries his face inside the crook of her neck – taking her by surprise.

I missed you, he mouths against the exposed skin. She giggles while shivers run down her spine.

"I missed you too," she playfully answers, then kisses him back. She brings herself more into his embrace and looks up to meet his eyes as she speaks. "And I'm glad I came back home in time to see you and Ana lip-syncing to a Taylor Swift song. You guys were adorable."

She chuckles as images of the moment are already coming back to her mind.

"Can you believe she picked the song?" Jake jokes. "I think my job's done here. Taught her all the best things in life." He amusedly brags, and Amy rolls her eyes.

(She can't help but smile a little too – because he definitely is an amazing father and best teacher of life.)
