After a long time of not updating this, I finally finished it. Sorry for not doing it in a long time. Anyways, I've got my inspiration back so I'm back in business. So please enjoy the story. And sorry for the grammar errors, I didn't get a chance to proofread this. I seriously want this done fast and painless.

Previously on My Little Family:

The two continue on their conversation happily. It seems like some of their trouble were solved bit by bit with reassurance that everything is going to be okay. But there is something that Tsuna is a bit worried about. Not that he would tell the other male about it. But once Matthew is gone, would their relationship still be the same or change little by little? Tsuna could feel his chest thumping lightly.

The thumping and talk came to a stop when the two heard crying coming from upstairs. It seems like Matthew is done with his nap. Tsuna suggest the other to rest since he was probably tired and that he would take care of it. Yamamoto didn't really say anything, knowing that his friend wouldn't take no for an answer. The brunet walks away to see Matthew in his room.

"Seriously, I'm not sure if I'm the one that's getting Tsuna's attention or Matthew is…" Yamamoto said, not sure if he should be happy or not.

Chapter Four: Lion's Den

As said, three males are preparing themselves to head down to the zoo. It's been a long time since they went when they were kids during the time. The last time they went to something that was close to a zoo was Kokuyo Land. And Tsuna almost lost his life during the entire event. And there's no way he's going to bring Matthew to such a dangerous place. Not when there is a chance of Mukuro being there.

"Well, let's go now since we're done." Yamamoto said excitingly.

"Yeah, before it gets too crowded."

The three males head out after securely locking the door. Since the zoo is a bit far from where they are, it's going to take a bit of walking. Matthew was busy playing with his new stuffed lion. Since the baby received the toy, he won't go anywhere without it. Tsuna tried to take it away before but Matthew would just scream at him. But more of a begging tone than anger.

"I hope it doesn't rain today." Tsuna mumbled.

"With a nice day like this, I doubt it would."

"Yeah… Maybe I'm thinking about it too much."

After an hour of walking around, the three arrived. There were people coming and going from the zoo. Yamamoto walked over to the ticket counter and asks for three tickets. He walks back to give it to the brunet and the baby. Matthew smiled as he twisted it around. It seems like the baby is having fun before going in. Tsuna rolls the chair as the three went in the zoo.

"I hope we get to see the penguins."

"Oh, is that so? I never thought you would be so excited Tsuna." Yamamoto chuckled.

"I-I thought Matthew would be excited if w-we were." Tsuna stumbled over his words.

The taller male ruffles the brunet's hair. Tsuna nervously frowns at his friend. He feels like he's getting teased unintentionally. The first thing they visit was the penguin. The younger male sure was overjoyed when one of them came close. But his hand did get wet from the icy water. After that, it was the monkeys, bears, turtles, tigers, and much more that they lost count. But Tsuna couldn't forget how they had to run in the bird area. It was feeding time…

They settled down on a bench after hours of walking. Matthew fell asleep a few minutes ago. He was snuggling comfortably with his new stuffed lion. Oh, how Tsuna envy the little one. Yamamoto leans back on the bench, putting his arm on the top of it. It's been so long since he had fun and feels tired at the same time. He glimpse at the brunet, who is wrapping Matthew with his light blue blanket. He sneaks away.

"Yamamoto, I think it's about time to go home. Matthew needs to sleep early." He said.

Tsuna turned to the empty space next to him. He could see the Yamamoto's invisible outline. Okay, where did his baseball loving friend go? Did he decide to go home without him knowing? From the looks of it, yes he did. He pouts angrily. Maybe going with Gokudera would have been a good idea. The boiling anger simmered down when he saw Yamamoto heading his way and with a vanilla ice cream. He hands it to the brunet.

"Here, you must be hungry." He offered.

"I'm not really that–"

Tsuna tried to protest when his stomach grumbled. Never rely on an empty stomach when you're arguing with someone that you're not hungry. It normally goes wrong. Yamamoto laughs lightly at Tsuna's attempt. The brunet takes the ice cream and bites the swirly top. It was delicious with a good amount of sugar. He resumes licking it by the side. Yamamoto looked at the baby and back at the brunet again. Tsuna was enjoying his treat. Out of sudden, Yamamoto felt his stomach rumble lightly. He was feeling a bit hungry himself. The taller male stared at the brunet once more. Maybe he could be daring for a minute. He leans in closer for a quickly before pulling back. He smiled.

"Ah, that's really tasty. Maybe I should get one myself."

Tsuna looked at his friend shocked. He then turn away and went back eating his cold treat as if nothing happened. The two males didn't really say anything. They just sat there doing what they wanted. Tsuna had to finish the ice cream which ended up as a great distraction to get his mind off what his Rain guardian did. Was that a friendly thing that friends do? If it is, he sure didn't know about it. Or was that considered flirting? Then again, who is he kidding? This is Yamamoto he's with. The only thing that he likes, or probably loves, is baseball. And he bet a million dollars on that right now. He continued eating it, pouting. As he did so, he glanced sideways to see Yamamoto who is somewhat sleeping.

"Yamamoto?" He called out.

But the taller male didn't respond. He was practically asleep like a dead light bulb. Tsuna sighed. He probably didn't get much sleep last night. The brunet was guessing that while he was in a deep sleep, Yamamoto must have heard Matthew crying during the night. And knowing him, he took care of the baby on his own without the brunet's help and concern. He looked at Matthew and looked back at Yamamoto again. He couldn't help but think that Matthew sort of resembles them if they ever had a child. That is unlikely and impossible to happen ever. Well, in this case, the two are Matthew's substitute parents for the time being. So, could he consider the three as one big family? The brunet isn't so sure anymore.

"I guess father like son is out of the case…" Tsuna thought.

Tsuna threw the last bit of the remaining ice cream into his mouth and stood. He needed to throw away the wrapper. However, he's debating if it was okay to leave while both Matthew and Yamamoto are asleep. Maybe he should take the baby boy with him in case. But Yamamoto is with him so nothing will happen. Then again, the Rain guardian is sleeping so that might end differently. Tsuna furrowed his brow. Should he wake up the other male? But he probably needs the nap and it would be unfair if he did so. The brunet looked around to see any nearby trashcans. There was one but you needed more than walking to get to it. The brunet looked at the Matthew. He'll just run really quickly.

"Wait here for me okay Matthew? It won't take that long." He whispered.

Matthew continued to snooze away. Tsuna smiled before rushing over the trashcan. A minute later the baby boy woke up. He looked around to only see Yamamoto sitting on a bench sleeping. And there was no sign of the brunet anywhere. He then reached out to the taller male as he cooed. The constant movement shook the stroller slightly. Eventually it moved backwards as it rolled further and further away from Yamamoto. Matthew blinked as he continued on reaching for the other male. Before he knew it, the stroller rolled backwards. Because of the position of the wheel, it turned him to the front. But it didn't stop there. If the rolling baby chair doesn't stop, it would mean he'll crash into the lion's den.

Matthew laughed happily at the speed he was going at. It wasn't too slow but it wasn't too fast. So there wouldn't be any problem even if he crash into something. The people that passed him gasped in shock. At one point, the baby boy waved at a woman carrying her baby as he rolled by. Thanks to how the zoo was built, it more of a small slope and if you continue going down, it becomes a flat surface. The stroller slowed down when it gently hit the bars of the lion's den. He clapped happily as he cheered for more in his baby language. From all that excitement, the baby boy failed to notice one of the three lions walking towards him.

Yamamoto woke up to the sudden shout from Tsuna. He quickly stood from the bench and looks around, dazing a bit. The Rain guardian later became fully awake when he saw how scared the brunet looked. The younger male was looking around frantically while muttering something under his breath. It was hard to say what he was saying but it was one consistent word. Yamamoto relaxed a bit and smiled at the other male. He placed a hand on Tsuna's shoulder and asked what was wrong. The brunet took his time and looked worried. From what he could tell, it was like he was debating on telling what was wrong or not.

"Matthew… Matthew, he's gone." Tsuna said weakly.

"What do you mean by 'gone'?" Yamamoto asked.

"He was here when I left but now… He's gone. It's my fault."

Tsuna was having his own panic attack. His words only confused the Rain guardian. Yamamoto patted the brunet's back gently as he soothes him. Eventually, he calmed down enough to explain the situation. With every word, Yamamoto listened carefully. He learned that Tsuna left a few minutes to throw away the trash. The Rain guardian and the baby were asleep, so he thought it was okay. However, when he came back, the baby is missing. Yamamoto merely pats Tsuna's back to calm his nerve down. He gently whispered that they'll find Matthew somewhere.

"Don't worry… Everything is going to be okay. I promise."

Tsuna was search all over the zoo with Yamamoto right behind him. He called the baby's name repeatedly as he ran. It was thanks to a large crowd that the brunet was able to find Matthew. However, his blood ran cold after seeing something he shouldn't have. There, in the lion's cage, was Matthew playing with the lions happily. The large animals surrounded him, waving their tails back and forth. There were even some that did their own business while being near the baby. Tsuna's heart sank to the bottom of his stomach. Yamamoto gasped harshly at the sight.

"Did someone call for help?" A woman asked.

"How did that baby get in there?" A man close to the cage asked.

"Whoever the parents are, they are irresponsible!"

Tsuna ignored the chattering as he pushed his way through. He reached to the front and called Matthew. The baby merely looked up to the brunet and giggled. In some way, the brunet was happy that Matthew was okay. However, he needed to get him back safe and sound. Yamamoto was right behind him, thinking of a way to get the baby boy out. That was when an idea came to Tsuna's head. He just needs to go into Hyper Dying Will Mode. After that, he'll fly on top of the cage, melt some parts of the top, and quickly get Matthew. And that's what he did.

The lions were just in the way. One of the lion that was closer to the baby looked at Tsuna. Their eyes locked as if they were in a staring contest. After a while, the lion roared and the rest of them separated and allowed Tsuna to take Matthew back. They knew that the brunet didn't have any intentions of hurting them or the baby. Matthew was just lying around, flinging his fist as if nothing is happening. He smiled and giggled at the sight of Tsuna. The brunet picked the baby up with one hand and used the other to fly out of the cage. The two males reunited with Yamamoto once they were on the other side.

"Thank goodness he's safe." Yamamoto smiled.

"Yeah… I think this is more than enough excitement for one day. We should go home." Tsuna insisted.

"I agree. Let's go."

Being able to be home made the Tsuna and Yamamoto feel relief. Matthew was in his own bedroom, asleep. The two of them were in the living room. They were trying to relax but found it hard to do so. They were still feeling on edge after the incident at the zoo. If Reborn were to hear this, Tsuna might need to consider writing a will. The brunet turned his head to the side. Yamamoto was lying next to him with his eyes closed.

"Sorry about today Yamamoto. I thought we were able finally relax and have fun… But in the end…"

"Don't worry Tsuna. I'm just glad that you two are safe. Though, we shouldn't go back there for a while."

"I can agree to that."

I know it's not much, but it's better than nothing. I hope this… ended well for everyone. Yeah, I really don't like this one. But you know… Always finish what you started. So, thanks for waiting on this story and hopefully a new chapter will be updated.
