Kyungwon open his eyes slowly and saw a white celling.He can smell a medicine.
He look around and realiase that he was at a hospital.

"Kyungwon?you awake?oh my god,"a girl was beside him.

"Where's my parent,?"he don't know who's that girl so he asked about his parent.

"They just go home to clean themselves,I'll call the doctor to check you so don't move,"she said and left.

Kyungwon frown.

"Who's that girl?why is she acting like she was really close to me,?"
He move a bit and felt a pain at his chest.

A doctor come and check him.

"Your condition is good Mr.Kang,"he smile.

"Oh,"

"Ok..I think all was alright but don't move to much cuz the affect from the your heart's surgery still not heal fully,"

Kyungwon nod and that doctor left.

It's become silent.

"Well..how you felt right now,?"

"I'm fine but still a little bit pain on my chest,"

That girl nod.

"But..can I know who are you,?"he ask and look at that girl.

That girl shocked.

"Y-you don't know me,?"

He shake his head.Kyungwon can tell that girl was disappointed by looking her reaction.

"Owh..then I'm Kim Minkyung,your friend,classmate and neighbour,"
she take out her hand for a handshake.

"Kang Kyungwon then,"he handshake with her.

Why did my heart pounding so fast?
Kyungwon thought.

Kyungwon's parent arrive there but the doctor call them.

"What's it doctor,?"

"Like what I said before this about the affect from the surgery,"
he stop awhile and continue.

"He lost his memory but he can get it back,"

"How long to get his memory back,?"

"5 months or maybe a year,"

"Why so long,?"

"He only have a memory about his childhood,so if he want his memory after his childhood,you need to help him to remember,"

"How about his heart,?"

"There are nothing wrong with his heart right now but idk about the future,so you need to bring him here for a check up,"

"Can we bring him to the house,?"

"You can but after 3 days,"

They nod.

"Thanks Mr.Lee,"

He nod and they left.

"Kyungwon,Minkyung,"

"Mom,"

"Aunt,"

"Thanks for helping us taking care of him Minky,"

"It's ok Aunt,"she smile.

"Kyungwon are you ok,?"

Kyungwon nod.

"Aunt,Uncle I need to go now,I have something to do at home,"

They nod and Minkyung left.

"Kyungwon,do you remember anything about your past,?"

He shake.

"My childhood only,and..mom who is that girl?she said that she was my friend,classmate and neighbour,"

"And your crush,"his dad add.

"Eh,?"

His parent just smile.

"Ok..what is that supposed to mean,?"

"You used to like her before,"said Mr.Kang.

"Am I,?"

They nod.

"You and Minky become a friend after we move at that neighbourhood,"

"About that crush part,?"

"We saw you and her kissed,"Kyungwon blush.

"You should rest now,"

"Mom..can you give me my phone,?"
Mrs.Kang give the phone to him.

"Thanks..,"

"We need to go now,we'll come here back at night and you can go home after 3 days,"

Kyungwon nod and they left.

He look at his phone and he open it.His phone wallpaper was his friends but of course he don't remember that.He go to the gallery and a lot of picture he with Minkyung.

"She pretty in a picture..but more pretty in person,"he mumbled.

Suddenly the door open by someone and it were his friends.They look at him with a worry.

"Kyung are you ok,?"a stone guy asked.

He frown.

They were the guys in my wallpaper,he thought. 

"Y-yep,but..who is you guys,?"

"Oh..he really lost his memory like what Minkyung said,"

"We were your friends,"

"I'm Yebin,this is Eunwoo,that Sungyeon,Kyla and this stone is Nayoung,"

"I'm sorry but id remember,"

"It's ok,we can help you to remember it,"

"Really,?"

They nod.

"Of course, we were your friends,"

Kyungwon smile.

"So..how is my behavior before,?"

"Well..you like to put a prank to a people and tell a lie especially to us,"
Eunwoo said.

"Last time you said you was a grim reaper and the next day you said you have cancer which was true,but we dont believe you and you go to toilet,we want to prank you by putting a tomato in your foods and it's end up you don't show up until the recess time end,"Yebin said.

"You was a basketball player like me,"Nayoung said.

"Is there my classmate among you guys,?"

"Nope,us four young than you except Nayoung hyung,"

They continue to talk and Kyungwon keep laugh because of Eunwoo and Yebin's story about him.

"Wow..I'm really that bad,"

"You right,"they said .

"When will you get out from here,?"

"After 3 days,"

"Oh that good then,let's hangout after you get out,"said Eunwoo.

Kyungwon smile. 

"Guys,do I have relationship with Minkyung,?"

"Of course noona was your friend hyung,a close one,"Kyla said.

"No..I mean like special relationship,"

They nod and look at each other.

"Well we not really sure about that,but I think you have a feeling to her before,"Yebin said.

"How did you know,?"Nayoung ask Yebin.

"They way he look at Minkyung is like the way you look at Kyulkyung,"Yebin smirk.

Nayoung smack Yebin's head.

"Hyung!"

They laugh.

"But..why are you asking about that,?"

"Nothing,just asking,"

"Oh then we need to go now,we'll visit you after school tomorrow,"

Kyungwon nod.

"Rest ok,"they said and left.

After they disappear Kyungwon take his phone back but suddenly his head hurt.He
