Since they have no choice but to listen to Gojou's lullaby.

Fushiguro covered his ear and told Gojou to stopped, which annoyed Gojou as he refused to yield in.

Soon it become 12am, Y/n happened to call Gojou and was surprised to find the three kids were still awake.

"It's because Dad's lullaby keep us awake" Fushiguro speak out. And Gojou just pinch his cheeks like what he did awhile ago.

"Mom, Yuji and Nobara can't sleep without your lullaby" The two said ignoring Fushiguro and Gojou pinching each other's cheek.

Y/n felt like an arrow strike her heart as there cuteness reach her place.

Y/n asked Nobara to give the phone to Gojou who is currently bullying Fushiguro. They both are pinching each other's cheek.

"Dad is currently bullying Fushiguro" Nobara said. Y/n sighed and yelled his name out.

"Gojou Satoru" The moment Gojou heard his name was called out by you. He immediately detached himself from Fushiguro and grab his phone.

"Yes, y/n?"

"Don't bully the kids, Your supposed to take care of them, not bully them"

Gojou was about to whine about Fushiguro. "Your an adult and they are kids, It's natural they are acting childish, Just please widen your patience for them, okay"

Gojou sighed as he thought ' It's unfair' but he couldn't argued back at you. But doesn't mean he will stop. He will just wait for the right time to get a satisfying revenge at Fushiguro.

Fushiguro just stick his tongue out at Gojou. The more he grow old the more he become sassy and cheeky towards Gojou.

Five minutes later~

The three kids are back in bed and Gojou's job is to give them a gentle pat while y/n, sing a lullaby for them.

Two minutes of y/n singing a lullaby, the three kids start to yawn. And Gojou Well, he fall asleep faster than the three kids.

His long arm that he used to pat the three kids is now weighing them down. And he snore loudly in there ears.

The three kids who was sleepy is wide awake. because of Gojou falling asleep before them. They all worked together to remove his arm that is heavy.

And Fushiguro suggest they all return the favor. By aggressively waking him up.

"Dad shouldn't sleep before us!!!" Nobara and Itadori yelled out at his ear.

Gojou immediately sit right up as he was surprised.

Fushiguro was delighted that his plan have worked.

So Fushiguro happily went under the blanket and sleep beside the other two.

The next day

The three kids woke up late. They stare at Gojou with a grumbling tummy. Telling him, they are hungry.

During that time, Gojou was humming while cooking.

"Did you guys already brush your teeth and wash your faces?" Gojou asked.

Itadori and Kugisaki shake there head as a No, While Fushiguro he already went ahead to wash his face and brush his teeth. Gojou shoo Kugisaki and Itadori to the bathroom.

Fushiguro give Gojou a deadpanned expression. As he grab Itadori and Kugisaki arm inside the bathroom and locked the door at Gojou's face.

*That brat* Gojou thought but decide to ignore and focus on there breakfast instead.

Meanwhile at the bathroom. Fushiguro just helped Kugisaki and Itadori to wash and brush there teeths.

It felt like Fushiguro become there older brother. With his tiny hands he pushed the stool near the sink. He even taught them.

Kugisaki climb up the sink to get her toothbrush and Itadori's. They both were working together.

"Itadori, don't dip your arms, Your sleeves will get wet" Fushiguro said and approached to fold Itadori's sleeves. Itadori let Fushiguro rolled his sleeves.

"Thanks, Fushiguro"Itadori replied with a smile as he vigorously washed himself.

While kugisaki tried to fold her own sleeves, But she couldn't, So she arrogantly approached Fushiguro for help. Of course, Fushiguro declined as he didn't like the way she asked him for a favor.

Good thing that Itadori was there as there communication bridge. Itadori explained that, since she's the one whose asking for a favor. She should asked politely. Fushiguro just nod his head.

Kugisaki yield in and asked Fushiguro politely this time. Which he gladly do it.

And so they washed themselves properly.

After preparing breakfast, Gojou went to the bathroom to check, if they all done.

"Breakfast is ready, Megumi, Nobara and Yuji"

They all go marching to the dining room. When they reach the table. That's when they realized that there short, small limbs can't climb to there chairs.

It was a cute struggle and Gojou love to tease them along with y/n. Gojou is fully aware that he is torturing her by sending those videos.

Y/n's reaction when she saw there adorable videos. *I want to go home, Now*

Itadori and Kugisaki immediately seeks help for climbing the chair, so they can eat. Fushiguro frowned as he didn't want the idea of Gojou helping climbing his chair.

Gojou snort at how many times Fushiguro failed to climb his chair, Making Fushiguro frowned further.

Y/n have predict this will happen, so y/n message Gojou that he make sure they won't hurt themselves, when they fall.

Kugisaki, Itadori were waiting for Fushiguro to climb and eat.

Since it taking him too long. Gojou was getting impatient as well so he grabbed Fushiguro and put him down in his seat.

Fushiguro struggle like a cat when he was carried.

*What are you a feral cat, Megumi" Gojou thought.

"Okay, Let's dig in"

"Itadakimasu" they all said.

"Dad, could you please pass me the syrup"

"Here you go, Yuuji-kun" Gojou said.

Kugisaki climb up the table to reach the bacon.

"Dad, Gimme lots of bacon"

The two were keep asking for help while Fushiguro eat his food peacefully.

"What's the matter, Megumi, Do you also want to asked me for help"

"..." Fushiguro frowned and choice to ignore Gojou's taunting. But when it's time for him to get himself a water.

Fushiguro knocked over his glass. And Gojou chuckled at his clumsiness.

"Geez...your so clumsy, Megumi"

Fushiguro pout as he finally tear up. He wasn't oblivious about Gojou's attitude. Which caused Gojou to panic.

"Dad is such a bully" Fushiguro said between his sniffle.

Itadori and Kugisaki tried to stopped Fushiguro from crying but then his sadness was contagiousness that Kugisaki and Itadori end up crying along.

Gojou immediately seeks your help. As he was panicking on how to calm down a three crying child. Of course, y/n wanted to scold him but the three kids comes first.

"What's the matter, Megumi, Nobara and Yuji?"

"Mom..." They all three said in front of the phone with a sad expression.

*They look like sad puppies, I seriously want to go home now* y/n thought.

"Why are you crying, Megu?"

"Because Dad is being mean to me"

*That guy, noted to give him a proper lecture when I get back home*

"Gojou's being mean, what did he do to you?"

"Mom, I missed you, When will you get home" Itadori and Kugisaki said at the same time.

*Ahhhhhhhhhhhhhhhhhhhhhhhhhh, I seriously want to take the car and drive back to there sides*

While Gojou was keeping a low profile to avoid a heavy punishment. From y/n and Principal Yaga, They will punished him for making his grandsons and granddaughter cry.

"Sorry to interrupt your phone call,

Y/n-senpai, But I have finally found a lead to it" Nitta called out to y/n.

"I understand, Megumi, Nobara, Yuuji, Mom got to go now, I promise as soon as my mission is done, I will go home as soon as possible" y/n said.

"Promise?" The three said while sniffling in front of the phone.

*I seriously want to go home and comfort them, But if I won't do my job a lot of people will die, Urgh...Hang in there me*

"Yes, Promise"

"Okay...Bye Mom" They all said

Before y/n ended the call she called out to Gojou "I remember this Gojou, your dead when I got there, you hear me"

"Ahahaha, okay, Y/n, I love you, Bye!" Gojou abruptly said and ended the called.

He is indeed screwed. Y/n at the other side of the phone glaring at her phone.

"Are you alright, y/n-senpai?"

"Yeah, I am, please continue"

*I'm super duper lucky to be assigned to help y/n-senpai! She's really different from all people I worked with. She's calm and collected, And much more she's strong and kind, Calm down Nitta, You have to focus, Do not mess up* Nitta thought as she excitedly explained everything.

Y/n just smile at her and told her to slow down, so she can understand it clearly.

Back to Gojou and The three kids.

They all stare at Gojou with a snot in there faces.

"I get it, I get it, You don't have to stare at me with those puppy dog eyes" Gojou said while sighing to himself.

He bring out a lot of picture book.

"Mom, We want mom" The three kids said.

"I understand that you missed y/n, even I missed her"

*I miss teasing her as well" Gojou thought to himself.

Megumi went towards Gojou and give him a hug. No more like wiping his dripping snot at Gojou's clothes.

At first Gojou was touched that Megumi is finally acting cute for once. But when he felt something wet.

"Ah! Your snot!" Gojou said as he immediately rushed to get a napkin to wipe Fushiguro's snot. Kugisaki and Itadori approached him as well and tugged his pants and point there noses.

After the snotty crisis, It was time for the real challenge. How did y/n manage this energetic three bomb at the bay.

*Yuuji is a happy energetic kid, While Nobara, she's a moody kid, Nothing change, And lastly Megumi an Feral brat, no more like a cat* Gojou thought.

Gojou imagine Megumi as a lonely cat but when Gojou tried to touched Megumi. He immediately hissed at him.

"No! Mom can only pat me" Megumi hissed to Gojou.

"Oh, Look this is so pweety" Kugisaki said while picking up the picture book.

"What is it?" Itadori curiously peek at the book that caught Kugisaki's attention.

"Wittle mermaid" Kugisaki said while shoving the book at Itadori's faced.

Gojou snort while watching.

"You mean, Little Mermaid, Nobara"

"Yes, Wittle mermaid!"

"It's Little not wittle" Fushiguro correcting Kugisaki.

"That's what I just said" Kugisaki replied.

Fushiguro sighed to himself and decide not to argued back.

Itadori and Kugisaki shared the same picture book.

"SEA!!!" They both said.

Which caught Gojou and Fushiguro's attention.

"Dad, I know where we want to go!"

"Oh! where do you guys want to go?" Gojou curiously asked.

"I'm good wherever we go, As long Mom is with us" Fushiguro said.

Kugisaki nod her head at Itadori as a mutual understanding as they both show the book about the little mermaid.

"WE WANT TO GO TO VISIT LITTLE MERMAID!"

"Little Mermaid is not real" Fushiguro said not even looking up to see their expression.

Gojou chuckled and agree with Fushiguro.

"Yuji, Nobara, Mermaids aren't real"

"But, but, the book said"

"That's a story book, All written in that book is just a fantasy"

Kugisaki was about to burst in tears and Fushiguro have predict it.

*Dad sucks at taking care us, his only expert on making us cry, I miss Mom"

"Kugisaki, Little Mermaid isn't real but the sea, Is real" Fushiguro said as he nudge Itadori to back him up.

"Yeah, The sea is real, it's like a huge pool that you can swim"

Fushiguro nod his head. After discussing where they will go when you got home. Itadori and Kugisaki immediately climb at Gojou and peek through his phone to make sure that he message you.

Fushiguro start to yawn and climb up at Gojou's lap to rest his head on his chest.

"Megumi, if your sleepy, go sleep at the room" Gojou said while messaging you.

But Fushiguro was already asleep. Gojou took a selfie of him along with the three kids.

Gojou message y/n.

Y/n, The kids want us to go to the beach, So don't forget to buy a swimsuit, I can't wait to see you in it ;)
