"Hey,it's 5cm per second..."

"Huh,what?" 

"The velocity of a cherry blossom petal when it falls,5cm per second."

"Hara,you know trivial thing like that?"

"Yes...hey, it looks like snow, doesn't it?"

"Is that so?"

"Hehehe. I...hope that we can watch the cherry blossom together next year too."

"Well, that would be difficult. Cherry blossom didn't grow in Korea"

"Then... let's go to Japan and watch the cherry blossom together again when we get older,okay? It's a promise then."

"Umm..okay. It's a promise. Let's make a 'pinky promise'."

"Goo Hara and Yong Junhyung will meet here again together in the future."

"Promise made!"
