Eunbi can't forget her bestfriend Daehyun who died in 2003 when they both were 5 because he had a cancer. At first, she can't believed it when she knew that her bestfriend had a cancer. Why him? There were a lot of people but why him? She can't accepted the truth. After Daehyun died, she never came out from her room. Eatless and didn't want to go to school. Her parents tried their best to make her be like other kids. But, she still didn't want to come out. Something happened when she saw a boy being bullied from her window and that boy cried and didn't do anything. She went out to save him. She didn't know why she wanted to help that boy. After that they become friends untill now. His name is Jeon Jungkook. Her parents felt really happy when they saw Eunbi smiled for the first time after Daehyun died. Eunbi thinked that God sent him to make her smile again. But, she will not forget Jung Daehyun forever in her life. The only person that can make her smile is Jeon Jungkook. Her parents are her happiness. 

But....

Something happened in her first day of school. She found a photo on the ground and she picked the photo. She looked at it and suddenly her eyes went wide. 

"What's wrong?" Asked Jungkook. 

No, this is not him!

He died. 

No!

"D--Daehyun...." She stuttered.
