"Seong Im!" Jong Kook yelled, waving his hand in the air. His little voice was heard by the little girl even from a far distance.

She ran his direction to meet him. "Jong Kook oppa!" When she reached him she was out of breath but continued to talk anyways. "I heard you were going to move house? Waeyo? Don't leave me!" The girl begged, almost crying.

Jong Kook felt bad for her. He was five years older than her, so he understands more than she does. "Sorry. But appa has to move job." Jong Kook said petting her head.

"Eomma said to give this to you. A necklace so that we won't forget about eachother!" He holds up two necklaces that has a metal plating on them. Engraved to one of them is "KJK" and the other "CSI".

"See, it has our initials written on it. I'll take the one that has your name, and you take the one that has mine. This way we'll never forget about one another!" He said, showing her a big toothy grin.

"Promise you won't forget me?" She asks holding her pinky up.

"Promise. I will never forget about you Cheon Seong Im." He raised his hand to intertwine their pinky together.

Jong Kook and Kwang Soo were hanging out and chatting until Kwang Soo noticed something. It was hidden under his shirt so intentionally. He purposely hid it so that no one can see it. "Hyung, can I ask you what that necklace is?" Kwang Soo asked pointing towards his neck.

"Ah, this thing? It's nothing." Jong Kook replied shortly and stuff the necklace deeper into his shirt. Kwang Soo was dissatisfied with the answer he got. And so, he does what Kwang Soo always does. He nags.

"Oh come in hyung! Tell me, tell me! Pleasee~!" He begged as if he was a child begging to get a toy.

"Yah, stop it. You're an adult stop doing that." Jong Kook was annoyed at his childish act.

"If you tell me then I'll stop." He negotiated.

Jong Kook sighs. "It's just a necklace from my childhood. There's this girl I was friends with since she was a baby. When she was five I had to move house. So my mom decided to engrave our initials onto the necklaces. This one have her initial, while hers has mine. I don't know how's she doing, all I hope is that she's doing great." He told him the story while looking at the necklace and fidgeting it.

"Do you like her?" Kwang Soo asked bluntly.

Jong Kook choked on air. "Mwo?"

Kwang Soo shrugged. "Just had a thought."

Jong Kook looks back at the necklace.

"Maybe I do."

Ji Hyo stands in front of the bathroom mirror playing with her necklace. 'Does he not remember? Maybe he just doesn't know? Maybe he never noticed my necklace?'

She was sad that he hadn't remembered her. 'Or was it a different Kim Jong Kook?' She was having a dilemma between either him forgetting her and she thinking of the wrong guy.

She never saw him wear a necklace. Or maybe he just doesn't wear it? It HAS been so long. She was just so confused. She laid her head on top of her arms on the countertop. She stayed there for a while until her phone rang. She reached out and grabbed her phone.

Without looking at who's dialing her she just picked it up. "Hello?"

"Ji Hyo-ya, are you busy?" Ji Hyo was surprised when she heard Jong Kook's voice behind the phone.

"Ah, oppa. No. I'm free today. Why? Do you need me for something?"

"Ani, I just wanted to know if you would like to hang out? Me and Kwang Soo were planning to go together but I wanted to invite you too. Can you come?" Jong Kook invited her.

"Yeah, I can. Send me the restaurant address and I'll be there."

"Arasso, I'll send it to you. See you there." He closed the call.

Ji Hyo groaned. She stood up and decided to change and go to the restaurant.

------------------------

"Ji Hyo-ya!" Jong Kook called, waving his hand from the table he and Kwang Soo sits. Ji Hyo immediately walked over to them.

They talked and joked, just hanging out, not really doing anything much, really.

They were eating while talking when Kwang Soo noticed something.

Ji Hyo was wearing a necklace. It was hidden inside the coat she's wearing. He looked at it and was surprised to find that it had looked like the one Jong Kook wore a few days back.

He never noticed she ever wore a necklace. It was weird how they both having matching necklac-, wai
