~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Shu and (Y/N) were in Shu's home at Raging Bulls, sitting on the couch in the living room, cuddling with each other.

Shu was sitting behind (Y/N), with his arms and legs around her and his head on her shoulder. He snuggled her there making her giggle.

"Hmm~ Shu do you remember how we met for the first time?~ *giggles*~"

Shu stopped for a bit and smiled,
"Of course I do. How can I forget how I met the love of my life?~ I am so thankful to God for that."

Flashback to 11 years ago:-

A teacher walked in her kindergarten class with a little girl beside her.

"Good morning, class. Today we have a new student in our class. I want you all to make her feel welcome and happy here."

Then she turned to the little girl and smiled,
"Please introduce yourself to the class, dear."

The little girl gave a cheerful smile and began,

"Hello everyone! I'm (Y/N) (L/N). It's nice to meet you and I hope that we can be great friends!"

"Hi there! Nice to meet you!"
A blue spiky haired kid smiled as he stood up, waving his hand. The little (h/c) girl, waved back.

"Alright, (Y/N), you can go and sit next to Shu. Shu, please raise your hand."

The teacher said as a white haired kid raised his hand up.

(Y/N) walked over and sat next to him, as the teacher started taking attendance.

"Hi, nice to meet you!"

The girl smiled extending a hand for him to shake. The boy smiled and shook her hand as he introduced himself,

"It's nice to meet you, too. My name is Shu Kurenai."

The whole time the two little kids talked and enjoyed themselves as Shu also helped her with her study work.

—————————————————————
(In the games period)

Valt, Shu and Xander were playing together as usual.

"Hey guys,have you seen (Y/N)?" The little albino boy asked his other two friends, who shook their heads in a 'no'.

"Maybe she is playing with her friends as well?" Valt said but Xander interrupted him saying,

"She's a new student how can she make friends so fast, Valt?"

"We should find her and ask her to play with us. The teacher also said to be nice with her, right?" Shu said.

"Yeah!"
The other two boys agreed and off the trio went trying to find the (h/c) haired girl.

------------------------------------------------------------------
After a while of searching, Shu saw her sitting all alone on a swing, with her head hung down. He walked up to her and began...

"(Y/N)? Why are you sitting here all alone?"

The little girl looked up at the boy standing in front of her with a sad face as she answered,

"Everyone has there own friend groups but I don't, so I have no one to play with."

Shu smiled as he offered, "Well do you want to play with me and my friends?"

"Are you sure? Will they want to play with me?" (Y/N) asked him as he quickly nodded.

He pulled her by her hand and said, "Come on let's go and play!"

They went all the way back to where Valt and Xander were.

"You found her, Shu." Xander smiled.

(Y/N) was a little shy so she shuffled behind Shu a bit as he patted her shoulder reassuringly.

"Hello! I'm Valt Aoi!" The cheerful blunette introduced himself.

"And I'm Xander Shakadera. Nice to meet you." The other muscular boy smiled.

"They're all very nice. You don't need to feel nervous." Shu reassured her, as she moved in front and introduced herself,

"I'm (Y/N) (L/N). It's nice to meet you all."

The whole day (Y/N) found herself in a family of 3 friends and enjoyed her time with them to the fullest.

------------------------------------------------------------------
(At the end of the day):~

The students were getting ready to go home and packing up their things. Valt and Xander were waiting outside for Shu.
As Shu was walking out, a certain (h/c) haired kid called out to him...

"Shu!"

He turned around only to find (Y/N) running up to him. The girl managed to catch up to him as she stopped in front of him.

"(Y/N)? What is it?"

Shu asked tilting his head curiously. The girl looked up at him and gave him a bright smile as she held his hand and began,

"Thank you for making the first day at school, the best!"

Shu blushed a little as he said, "N-no problem."

Then the girl opened her little bag and searched in it for a while and then took out a cute red and white bracelet.

She held out Shu's right hand and put it on and smiled.

"Why are you giving me this?" The whitette boy asked the girl.

"Accept it as a friendship gift from me." The little girl smiled as she continued,

"Hey, Shu?"

"Yeah?"

"Could you promise me something?"

"What is it?"

"Can we marry each other when we grow up?"

"W-what?" Shu's face reddened.

"I've been feeling something in my heart and I don't know what it is but my heart says it is the right thing to do. So, could you promise me?" (Y/N) pleaded with expecting eyes.

"I've been feeling something similar too! Yes I promise you that we'll get married in the future! I'll wear this bracelet everyday so I won't forget." Shu answered smiling.

"Yo guys, are you coming or not?" Xander yelled interrupting the cute moment.

"Coming!" Shu and (Y/N) yelled in unison as they ran towards the duo of Valt and Xander.

(End of flashback)
------------------------------------------------------------------
"And I still wear it." Shu smiled as he pulled down his glove a little, only to reveal the same bracelet that little (Y/N) had gifted him.

"You never forgot." (Y/N) smiled too as she turned around in his grip and sat facing him. She leaned her forehead on his as he said,

"How can I forget the promise I made to my love?"

(Y/N) hummed in response and Shu leaned in to give her a sweet kiss. Then holding her tightly in his arms and placing his head on top of hers, he began,

"I'm gonna keep that promise. We are getting married soon enough and then you'll be fully mine...Mrs. Kurenai~"

(Y/N)'s face turned red in embarrassment as she buried her face deeper into his chest. Then she mumbled something which Shu couldn't hear.

"Pardon? What was that my love?" He asked.

"I love you, Shu." Came a soft response.

"I love you too, (Y/N)." He replied smiling.

The couple cuddled each other for the rest of the night, enjoying each other's company.
