"I didn't know it could be this fun, "Yoona said with a laugh. When she felt a little dizzy, he stopped without saying anything. She paused the moving swing with her feet and turned her head to look at him. "Gu Shangyan?"
"Hmm?"
"Thank you, "Yoona whispered.
"For?" Gu Shangyan asked.
"Just thank you, "Yoona said with a smile.
"Then, I have to say something to you too, "Gu Shangyan replied. "I'm sorry."
"For?" Yoona raised her brow.
Gu Shangyan didn't know what to say and he said, "Just I'm sorry."
"Apology taken, "Yoona smiled. "Now tell me, do you have some cool books in your collections?"
"Hmmm….I don't know but I recently got a book. It's a fiction about a spy and set in the first world war era, "Gu Shangyan replied.
"Oh my god, will you show it to me?" Yoona asked him.
"Follow me, "Gu Shangyan said and she followed him.
