A/N: I am very excited to start a new Once Upon a Time fanfic and as I said in the summary, this will be a series of one-shots, so one chapter has nothing to do with the other one (most of the time). Some chapters will be short, some chapters will be long, some chapters will be angsty, some will be sweet, etc. Every chapter will start with a prompt that either I thought of or you sent in. If I don't choose your idea, it doesn't necessarily mean it's a bad one. It just means that I couldn't form the idea into a story. Alright, that's all I wanted to say. Have fun reading! (Sorry for typos)

Chapter 1: The Love of a Father

Prompt: Emma watching Killian play with their children and realizing how lucky she is. (Story takes place in the future) (Emma's POV)

It was a warm summer day and my husband Killian Jones and I sat on a bench and watched our children Jonathan and Alicia play on the playground. There were a few other children, but Jonathan and Alicia rather played with each other than with other children. I didn't care as long as they were happy, and I knew Killian thought the same.

"Isn't it funny how there's three years of age difference between Jon and Alice, but they get along so well when they play together anyway?" I asked, looked Killian in his eye and smiled. He just raised an eyebrow.

"I'm three hundred years older than you, but we can get along quite well too. No, I'm not really surprised, Mrs. Jones."

I raised my eyebrows, realizing how right he was. Then I looked back at my children. I was surprised when I saw Jonathan and Alicia play with another kid. It was Robin and Regina's kid, Kellan.

"Oh look, Killian. Do you see that?" I said and gave him a jerk against his arm with my elbow.

"What? The two most beautiful children ever created? Yeah I see that."

I rolled my eyes. "No, Killian. I mean yes, but look, they're playing with Kellan!"

"Sorry, love, but they are not playing. Kellan is trying to steal our children's toys! I'm going over there."

Killian stood up and I frowned. Was I really so blind to not see what was really going on? When I looked more carefully, I saw Killian was right. Kellan was holding Jonathan's little truck, Jonathan was crying and Alicia was yelling and trying to retrieve the truck. As a big sister of a younger brother, she always felt the need to protective. This, of course, was mostly a good thing, but sometimes it had its consequences. There was a possibility she was going to hit it out at Kellan in no time, so it was a good thing Killian was going to intervene. He squatted in front of the three children and asked what was going on.

"He stole my truck!" Jonathan cried, and pointed at Kellan.

"Is this true, Kellan Mills?"

Kellan shook his head. "No! Jonathan said I could borrow it!" He crossed his arms and looked angrily at Jonathan.

"Is this true, Jonathan?" Killian asked.

"No! Kellan is lying!" Alicia said, making Killian look mad at her.

"No one asked you."

I shook my head. Very subtle.

"Jonathan? Is this true?" Killian repeated and Jonathan shortly nodded.

"Yes, but I want it back now, daddy!"

"No, you can't have it back." Kellan immediately said and hid the truck behind his back.

Jonathan started to cry again Alicia swung her fist up in the air, ready to punch Kellan in the face. Kellan screamed and I almost got too scared to look.

This was getting out of hand. Shouldn't I help? No, I thought. I trust Killian. He must have a plan.

Killian took hold of Alicia, so she couldn't get closer to Kellan, for starters. I sighed in relief. No one was going to get hurt.

"What's going on here? I heard my child scream."

It was Regina.

"Kellan borrowed Jon's truck, Jon wants it back, Kellan doesn't want to give it. It's no big deal and I'm handling it. So if you don't mind…" Killian said and stood up, but didn't let go of Alicia.

"I'm sorry, captain, but if my son doesn't want to give it back yet, he doesn't have to. YOUR son lent it to him. If Jonathan wants to play with it, he shouldn't have given it to Kellan in the first place."

Oh no Regina, don't make this worse, I thought.

"Regina, listen. He didn't give it to Kellan, he lent it to him; meaning he wanted it back later. It's his toy, so he decides when he wants to have it back and Kellan should listen to him." Killian said and Regina raised her eyebrows.

"No, he shouldn't. I promise you, Jonathan will get it back. Today. But for now, Kel isn't done playing with the truck so leave him alone. Just find your kids another toy and they won't even remember the damn truck." Regina said and walked away holding Kellan's hand.

Of course Jonathan started crying again and Alicia started tugging on her arm. Killian shouldn't let her go now, otherwise hell would break loose. I hoped Killian would come up with another solution.

"Listen, darlings. What if we were going to build a castle in the sandbox? Would you like that? So you know, I'm very good at it and I'll help you both. What are you saying? Aye?"

Luckily Alicia and Jon's faces lit up. "Aye!" They both said and followed their father to the sandbox.

I smiled and watched them work together to make a beautiful sand castle. The children were clearly having fun and so did Killian. I suddenly got excited to join and stood up. I walked to the sandbox. "Hello to my tough boys and tough girl. Just a quick question: may I join?"

Jonathan and Alicia started cheering and clapping. "Yes yes yes!"

"Well, you heard it. Welcome on board." Killian said and smiled. I smiled back. I couldn't have imagined having a family more perfect than this. This was like a dream I hoped I was never going to wake up from.

A/N: I don't know about you, but I consider this as a very short chapter. Expect the other chapters to be longer (and better) than this. I would like to thank you for giving my story a shot and please let me know what you think in the review section. Remember, the next chapter won't be a sequel to this little story!
