When a girl and a boy become best friends, one of them is bound to fall in love with the other party. 

But what happens if your love is one-sided?

What happens if you're friend-zoned?

Her; Choi Sooyoung 

Age: 18

She's just a regular high school student in SM High School.

Her parents are successful lawyers which makes her pretty well to do but they don't like to flaunt it. 

She lives in a comfortable apartment with her parents and little brother, Choi Junhong. 

She laughs at the lamest things and like a normal human she is, she gets annoyed with certain things people do.

People try to up to Sooyoung because she's best friends with the hottest guy alive: Kim Jongin, also known as Kai. 

Most of them just want to be noticed by Kai because.. well, who wouldn't? He's hot, rich, suave etc. 

Everyone wants him. Everyone but Sooyoung of course. 

But things change, don't they?

Him; Kim Jongin aka Kai.

Age: 18

The hottest guy alive in SM High School. 

Kai is Sooyoung's next door neighbour and they've been best friends since they were young. 

He's the most popular guy in school and he's wanted by almost every girl in town. Even teachers can't resist his charm and good looks.

His parents are sucessful business people, humble and kind people.

He's friends with the most popular guys in school; EXO. 

Like Sooyoung, he has many secrets that he only shares with her. 

When he and Sooyoung are together, no one can get inside their heads or get between them. 

It may seem like Sooyoung and Kai are a couple on the outside, but they're just that close to each other. 

Kai only sees Sooyoung as a sister and best friend, nothing more, nothing less. 

Or does he?

The sound of a car horn made him rush to the window. Being a short 6 year old made it hard for him to see out the window, so he stood on his toes. 

"A moving truck?" he spoke. Out of curiosity, he continued to watch the scene outside his house. He knew someone had bought the apartment next to his family's but he didn't know who were the new owners of the apartment. 

"Jongin, what are you looking at?" His mother asked, ruffling his hair. 

"Mommy, the new owners of apartment 2B are here." his squeaky little voice said. His mother smiled and peered out the window to get a look. 

"Looks like you've got a new companion, Jongin." She said, lifting him up so he could see. A little girl, the same age as Jongin was holding onto her mother and father's hands, looking at the new house they were going to live in. She's even shorter than I am. He thought, watching the little girl with fascination. 

"Let's go, honey." his mother said, taking a step away from the window with him still in her arms. 

"Where to?" He asked, cocking his head to one side. 

"Downstairs to introduce ourselves." his mother giggled at her son's question before carrying him down the stairs. 

"What if their daughter doesn't like me?" Jongin asked as he held onto his mother's hands as they walked towards their new neighbours. 

"She will. Don't worry." his mother said, pulling him along. 

"Hello, I'm Mrs Kim and this is my son, Kim Jongin." Jongin hid behind his mother's long flowy dress, with his head poking out. 

"Ah, are you our neighbours? I'm Mrs Choi and this is my son Junhong." the woman introduced herself and her son, extending a hand for Mrs Kim to shake. 

"Mommy! Mommy! We got a swimming pool!" the little girl that Jongin had his eye on a moment ago came running from the inside of the apartment, bumping into her little brother on the way. Junhong started to cry and she quickly made funny faces to stop her brother from crying. Jongin watched silently as he watched her every movement. 

"Ah, that's my daughter, Sooyoung. A little bit clumsy as you can see." Mrs Choi joked as she called Sooyoung over. 

"Sooyoung, this is Mrs Kim and her son, Jongin." Mrs Choi said to her daughter. Sooyoung stared blankly at her mother before bowing.

"Nice to meet you Mrs Kim, I'm Sooyoung, age 6!" Sooyoung belted out. Mrs Kim giggled before turning to look at Jongin. 

"Go on, introduce yourself." Mrs Kim said, pushing Jongin forward. 

"Hello, I'm Kim Jongin, age 6." Jongin said as he bowed. 

"My, such cute children we have. I would invite you in for tea, but my house is barely furnished." 

"Well, that's alright. We can have tea in my house." Mrs Kim suggested. 

"That sounds delightful. Children, stay in the garden and don't hurt each other. Us parent's are going to have tea." Mrs Choi said, patting Junhong and Sooyoung on the head before walking in to the Kim's apartment. 

Sooyoung and Jongin looked at each other.

"You're funny looking." Jongin abruptly spat out. It wasn't intentional, it was just a normal thing for him to speak his mind.

"You're funny looking yourself." Sooyoung said and they both started to laugh at each other.

"Which Elementary school are you going to?" Jongin asked.

"Shohwan Elementary School. You?" 

"Eh, we're in the same school..." Jongin said. 

"NOONA JUNHONG HUNGRY!" Junhong yelled at the top of his lungs while tugging at Sooyoung's shoes. Sooyoung giggled before picking Junhong up in her arms. 

"Noona will bring you to Mommy, okay?" Sooyoung said before carrying Junhong into the house with Jongin trailing behind them.

"Give me your lunch, no teeth loser!" A boy not much taller than Sooyoung ordered, kicking sand all over her shoes and grabbing her lunch box.

"But it's my lunch...give it back!" She yelled, rushing forward to grab her lunchbox, only to be shoved to the ground by the boy's friend.

"That's not nice, boys." Someone said, placing a hand on the boy's shoulder.

"But h-hyung." 

"Apologize. Now." 

"Sorry Sooyoung.." The two boys said in unison before running off. 

"I believe this is yours." Jongin said, tossing Sooyoung's lunchbox at her.

"I always get picked on for my front teeth or glasses." Sooyoung grumbled as she dusted sand off her dress and picked up her glasses. 

"Come on, I'll eat with you." Jongin said, taking a seat under a tree before opening his lunchbox. Sooyoung grunted and stalked towards Jongin before opening her lunchbox angrily. Jongin laughed before snatching Sooyoung's sandwich from her hands and taking a bite from it.

"Hey!" She said. 

"I don't like tuna but you do. Eat my sandwich, please." Jongin pleaded. Sooyoung frowned but once she looked at Jongin's face full of jelly she instantly felt better. 

No one expected how close they became after that.
