Lu San and Li Seulbi.

After hearing those words from Mo Xung, Lu San froze. Then, he remembered the scene of two familiar silhouettes leaving the school earlier. He pursed his lips "Hey Mo Xung..You have seen my sister..So, tell me the one who was with Li Seulbi was my sister or not?"

Lu San was answered with silence. He frowned and shook Mo Xung's shoulder who was sleeping. Mo Xung didn't bother to get up. Lu San shook him hard but he was still in sleep.

Something dropped from Mo Xung's pocket as Lu San was shaking him. Lu San picked it up and it was Mo Xung's phone. Lu San smirked ' I can use this since my phone's battery is low.'

"Hey Bro..I am taking your phone to make a call. I think you will be fine, right?" Lu San whispered in Mu Xung's ear. Mo Xung didn't respond. Lu San sighed and shook his head.

' I am always amazed by his sleeping talent. He can fast asleep and once asleep he is like a dead person. I wonder which girl will fall in love with him..'

Lu San went to washroom and called his sister, Lu Reyi. The call went through and he heard his sister's sweet voice from other side of phone " Hello.Who's this?"

" Sis Reyi..It's me, Lu San." Lu San answered. Lu Reyi was shocked "Lu San..Aren't you in school?..Judging the time, the class must be going on, right?"

Lu San bit his lower lips " Yeah, I am in school. And indeed the class is running but i wanted to ask you something. Did you visit my school earlier?"

Lu Reyi softly said " Yes, I visited but you were neither in the class nor in cafeteria. But Guess what?!..I met your love today. " The word 'Your love' made Lu San blush but he was confused as well as shocked "Sis..How..I mean Who?"

Lu Reyi chuckled " You silly boy..I am your biological sister. There's nothing i don't know about you. Her name is Li Seulbi, Right? I saw her first time when she was small. She has become matured and chubby. I almost didn't recognized her. But then i saw the 'LS' necklace on her neck, that made me realize she was the one. She is so sweet. I like her."

When Lu San heard about 'LS' necklace, he smiled and looked at his own wrist where there was the thin silvery bracelet in which 'LS' was written. He recalled that day .

The sun was setting. In a park, A young cute boy and a girl were sitting on each swing swinging their little feet. They were Lu San and Li Seulbi. The park was not so crowdy. Their were few other childrens and their parents playing in the park.

Little Lu San got up from the swing and stood in front of Li Seulbi. He looked shy and nervous. Little Seulbi was confused by his action. Little Lu San took a step closer and took out something from his pocket.

It was a small box wrapped in gift wrapper. He bit his thin lips and handed the gift box in Li Seulbi's little hand saying " Open it. " . Li Seulbi looked at Lu San before looking at the gift box in her hands.

She slowly and carefully untied the gift ribbon and opened the box. There was a necklace and a bracelet. Both of them were of same designs which was thin and silvery.

It was shining by the reflection of the setting Sun. It was simple but the beautifully written 'LS' word in it made it look more magnificent.

Li Seulbi smiled brightly looking at the gift. "Is this for me and you?" she asked sweetly. Lu San nodded happily " Did you like it? I asked my uncle to make it personally by him from Paris."

Li Seulbi gasped " Wow..Paris. I loved it. Bro San, The word 'LS' written here is our name, isn't it?" Lu San was really happy that Li Seulbi liked it.

He proudly said " Yes, It represent our names. Lu San and Li Seulbi. Ok.. Now Let's wear it. The necklace one is yours and the bracelet is mine."

Li Seulbi was excited to wear the necklace. Lu San already wore the bracelet and it looked good on him. As for Li Seulbi, her little hands couldn't reach the back of her neck.

She pouted in frustation. Lu San chuckled and helped her wear it. After it was worn, Li Seulbi was looking more pretty than before. She said happily " This is so cute. Thankyou for the gift Bro San. I will keep it near my heart forever. "

Li Seulbi stepped closer to Lu San and hugged him. Little Lu San's little face became red . His heart was pounding so fast . He hugged her back and promised in his heart " I will only love you, Xiao Seulbi."
