10 years ago;

The full moon was lying in the middle of millions of twinkling stars and was s.h.i.+ning brightly in the sky .

There were two kids lying side to side in the gra.s.s facing the sky . They were Little Lu San and Little Li Seulbi . They both were enjoying the beautiful night view .

Little San suddenly asked " Xiao Seulbi, Do you like the moon?" Little Seulbi stared at him in confusion . She looked up at the bright moon for a while before replying " Do you know Moon has some dark spots? . . Look carefully you will see it . " Little Seulbi pointed at the moon . Little San arched his brows and also looked at the moon carefully .

Indeed the moon had some dark spots, But why she was mentioning it all of a sudden without answering to his question first . .

Little Seulbi sighed as she said " I like moon because we are alike . The moon has dark spots so Do i . But the difference is It's still beautiful while I am . . " She went silent . Little San sat up and looked at her " I also like moon . Do you know why?" Little Seulbi shook her head . Little San smiled brightly as the moon as he said " Because you like it . "

' No matter how many dark spots filled the moon, I still like it as it s.h.i.+nes beautifully, So do you . . You will always be my moon, my Star , my whole universe no matter how you look . ' He thought . Little Seulbi chuckled at his answers . She also sat up and ruffled his hair " You will never change . "

He smiled " Xiao Seulbi, I have an idea" Little Seulbi asked curiously " What idea?" Lu San pointed at the moon " I know i can't stay with you by your side everyday . So, Look at the moon whenever you miss me, You will feel that I am by your side . " Little Seulbi thought that was really a silly idea . So, she laughed and opened her mouth to tell something . But, Right at that moment, Someone called them out .

Mo Xia shouted from inside the house " Sansan, Xiao Seulbi . . Come fast . Dinner is ready . " Li Seulbi said " Come on, I am hungry . Let's see who reaches the dining hall first . " She started running . Lu San immediately stood up and ran after her .

*Bam*

The window closed with a loud noise by the force of wind . The noise made Li Seulbi who was daze having memory flashback return to her senses . She knitted her brows as she tried to remember further .

She couldn't remember what happened thereafter . She sat on her bed thinking about the memories she just got . " The boy just now . . Who was he? . He called me Xiao Seulbi . So, Maybe I was close to him . But I can't remember anything about him . I even didn't see his face clearly . " Li Seulbi murmured to herself .

She closed her eyes and tried her best to remember something . But beside headache, she got nothing . She sighed as she slowly laid in her bed . She couldn't fall asleep . Is it because I slept too much in the day or because of those unusual memories? She asked herself in heart .

She turned left and right but she couldn't fall asleep, No matter what . She sat up and looked outside the window . " Sansan, Xiao Seulbi . . Come fast . Dinner is ready . . " Suddenly the words rang in her ears . Li Seulbi caught the main point . " Sansan . . " Who is Sansan? My friend? Bestfriend?

'Wait the name is familiar, Sansan . . Sansan Where have i heard it . . Um . . Lu San . ' As She thought this, She felt unsually awkward . She laughed and slapped her forehead . " What am I even thinking? . He is prince and is a dreamboy of everyone while I am a frog compared to him . There are many Sansan in China, How could I know who he is? And I feel that was a memory of my childhood, So he must have grown up already . I think I should ask Yumi about it . Maybe she knows him . "

Li Seulbi said as she laid back to sleep . She was very curious about the mysterious Sansan, So that night she drifted to her dream world after a long time .

Meanwhile;

Lu San remembered how he slowed down his pace to make Li Seulbi reach first at the dining hall . He could easily remember her happy face that time . Those happy days with her were the most memorable moments for him .

He sighed . But those memories only existed for him not for her . He felt his heartache thinking that . He really wanted to enjoy every moment with her happily as they did in childhood .

He went back to his bed . He laid under the covers and closed his eyes to hide the immense feeling he was having that moment . ' From tomorrow, I will try my best . . '
