The Quads started Kindergarten when they completed three. Eunji and Junmyeon couldn't believe that their kids grewup so soon.

Irene was a sick baby and Eunji was always worried about her health. It was one of the cons for being born as a Quad.

They would never leave her alone. Even at the school they requested teachers to pay more attention to her.

"Mamaa...", Little Kai cried.

"When school is over mom will come to take you Kai...",  Junmyeon tried to calm him down.

"No skool for meee. Let's go... Mama", Chanyeol abruptly sat on the ground.

"Ah!! Chan listen to me. School is fun. You can play alot of games", Junmyeon lifted him up and the boy calmed down at the word games.

"Appa bye bye", Irene waved her hand and little Sehun laughed at his brothers.

" Boys...listen to me. Take care of your sister okay?!" Junmyeon requested and the brothers nodded in unison.

Everyday Kai and Chanyeol would cry alot when Junmyeon goes to drop them at school. The teachers had to drag them inside while Irene and Sehun would go calmly as they hold onto each others hand.

Kai somehow would end up losing atleast one of his belongings, especially his shoes or socks. It was a nightmare for both the parents. Luckily sometimes Sehun would bring them back in his school bag.

Chanyeol picked up the habit of eating erasers. Eunji tried her best but she wasn't able to stop his habit. 

The Quads had Christmas holidays and they were very excited when their father decorated a Christmas tree in the house.

Yixing's family from China had visited them. Yixing and Luna had another son named Tao who was three years old. The quads were cheerful when their two cousins arrived.

Luhan and Sehun are closer than the others but all the five boys adored their sister Irene as she was the only girl child.

"Some times I dress up Tao as a girl. I badly wanted a girl child but I got boys ", Luna giggled. 

" I dressed up Kai in frocks when he was a toddler even though we have daughter", Eunji grinned proudly.

And their husbands laughed at the women.

"Yayy it's Krismas", Chanyeol clapped as he ran around the big tree and Irene, Kai and Tao ran behind him.

"Chanyeol... don't ru-" Before Eunji could warn he tripped and fell on the floor. But as usual he didn't cry.
Kai and Tao fought for the extra cake piece and they cried when Sehun ate it.
"Lu here", he even shared it with his favorite cousin.

Quadruplets became very close with their cousins. And when Yixing and his family were about to go back, the quads cried alot.

"Jun wake up", Eunji nudged Junmyeon's shoulder but he pulled her closer for an embrace.

" Let me sleep few more minutes Eun", he spoke grogily.

"It's Monday and the quads have school. Please honey... You have to prepare the food", Eunji looked at the clock and they were already late.

Finally he got up and went to prepare breakfast while she went to wake up the kids.

Irene was already out of bed. She ran and gave her mother a hug.

"Good Morning sweetheart", Eunji ruffled her hair and rushed Irene to brush her teeth. Sehun woke up and slowly followed his sister to brush.

"Chanyeol get up", His mother pulled his ears and he opened his eyes.

"Come on now", She pulled him out of bed." Go brush your teeth", And forcefully made him brush.

Kai was still sleeping. "Kai wake up", He didn't move but Eunji could tell that he was awake.

"Kim Kai!!!" She nudged him again.

"I don't want Schooool", Kai whimpered.

" No excuses", Eunji lifted him up and he gave in.

Four of them queued up for bath. Eunji bathed them one by one and prepared them for school.It was such a hassle to prepare four kids.

Junmyeon fed them and while Eunji prepared their bags.

 Sehun spilled his food and blamed Kai so they started a wrestling match. Junmyeon's glare would set them quite.

One day Irene fell down while she was running at school. The parents found out that their daughter has Asthma. Eunji wished Irene was also born healthy like the others.

She so worried about Irene and always told her three sons to take a proper care of their sister.
Even Junmyeon was always concernd about Irene whenever she goes out to play.

Eventually, Chanyeol, Kai and Sehun developed habit to never let their sister to go out of their sight.

              The Kang family lived in the same neighborhood of the Kim's family. They had two daughters.
Sulli and Seulgi. Sulli was three years older than Seulgi. Seulgi was born in the same year as the Quadruplets. The girls father, Kang Yunho was a police officer.

From Kindergarten the Quads and Kang Seulgi were in same class but the Quads sticked together and played among themselves.

As a child, Seulgi had an intimidating aura. She seemed stronger than other kids, her classmates avoided her.

Seulgi played alone and envied the Quads. They looked happy all the time and she wanted to become their friend.

When the Quads played in their neighbourhood park, Seulgi stayed alone watching her elder sister play.

          A kid grabbed Kai's chocolate when was alone and he started to cry. "Hey my choco. give it back", Kai cried awfully but was also afraid of that strong kid.

He looked around the class for his siblings they weren't present to help him.
