Seon Yein was standing outside the neighborhood

"ding dong" a woman came and opened the door

"He..hello !I'm your neighbor, Seon Yein..."

"Oh !Hello,Yein ! Please come in ! Wooseok ! Come here!"

A little boy came down

"Wooseok,meet your neighbor" 

"Hello,I'm Seon Yein"  Yein reveals a bright smile

"Kim Wooseok " The boy,Wooseok. Has a really good looking face,black eyes shining with confident. Also have him a little smile.

Yein didn't talk for almost one moment. He was shocked by Wooseok.

"Yein?Are you alright?" Wooseok was confused,why did this boy didn't talk to me for so long? Didn't he want to be friends with me ?

"...Ah sorry Wooseok ? Can I call you Wooshin ?" Yein came back from his thoughts,blushing immediately. "Because Wooshin is easy to pronounce..." He explained 

"No problem." "Thank yo-" 

"Can I call you Sunyoul ?" Wooseok asked suddenly

"Sun...youl? "

"When you smile,you're like the sun. It's warm" Wooseok smiled again.

"Ah okay! Nice to meet you, Wooshin!"

"And nice tomeet you too,Sunyoul."

1st grade 

Kim Wooseok entered the classroom,saw his little neighbor sitting on the floor  and playing toy cars

"Sunyoul !" He rushed to the bunny-like boy

"Good morning Wooshin!Are you and I in the same class ?"

Yein asked curiously,big eyes blinking

"Yeah...I think so,what are you playin? "

"Cars!Do you want to play with me? We can play car racing"

"Yesss! Can I get the red car please Sunyoullie !"

"Of course you ca- Wooshin! Be careful !!"

7th grade

In the library, Seon Yein saw his best friend sitting on the chair and reading his book

"Wooshin !" He rushed to the cat-like boy

"Sunyoul " he gave him a little smile "You're a bit late "

"Sorry Wooshin ! I promised I'll never late because of finding the social building,really,I promise !"

"I don't mind it actually, but if you want,you can ask me to come with you anytime. Then you won't be late again." Wooshin used his fingers to comb  Yein's soft black hair

"Come on lil'bunny, I've got some problems to solve,would you help me with that?"

"I'm not bunny Woohin. But of course I won't help you if you still calling me bunny." Yein blushed and gave Wooseok a serious face. 

"Ah~you're a little rabbit I know" Wooseok grinned 

"Kim Wooseok you're super annoying !"

Kim Wooseok often thought, what kind of relationship they are? Neighbor? Classmates? Best friends? Or even more...

Sunyoul might thought they just friends, but Wooseok doesn't 

"I want us to become lover" 

Kim Wooseok wrote in his science textbook. He should be preparing for tomorrow's classes right now,but he didn't have the mood to study. Instead,he thought of Yein.

Sunyoul,Yein,Seon Yein

"How can I be so easily in love with a person?" 

Seon Yein was finding the social building again,Kim Wooseok wasn't here due to his class hasn't over yet.

"I remember it's this way tho...? Why did all these buildings look exactly the same ?"

He kept walking toward the white building ,luckily this is the right place he wanted.

"Help!help me!Wooshin !"he heard Sunyoul's scream, and ran to him "Sunyoul ?Sunyoul !answer me !!" "Wooshin...I'm here..." "Sunyoul !are you ok?" "Wooshin, don't worry about me,I'm..." "Sunyoul ?Sunyoul !Yein !Yein !"

"Doctor, is he ok ?" "He needs to resting " "Let him goes to our house in countryside " "That means...Sunyoul must leave me?" "Yes,Wooseok. You know, he needs to resting " Wooshin clenched his bottom lip, clenched his fist

And Sunyoul leaves, 6 years 

" Hey Kim Wooseok ! Here comes a  transfer student !" "Ko Minsoo, be quiet !Let me get some rest " "He is so cute! You should see ..." "What's his name ?" "Umm...His name seems to be Seon Yein..." "Yein ?"

Is he my Sunyoul ?Kim Wooseok stands up and ran out the classroom, suddenly, he saw his little neighbor, his good friend, the person who he liked

Seon Yein 

"Sunyoul !" In the past ,we just friends , and you leaving me for a long time, but ,you back .This time ,I won't let you go , my Sunyoul.
