After the walk they had, they went back to Luhan's house. While walking home, Seori asked everything about Yoona. Yoona just answered that are necessary and Luhan added a bit about Yoona.

"Tonight, what we're going to do?", Luhan suddenly asked.

"Anything"

"Seori wants to sleep with Yoona unnie tonight. Can I?"

"Hmm sure, why not", Yoona answered while smiling.

"Hmm, what about if we sleep in the living room?"

"WAHHH, it's going to be fun!", Seori said, innocent.

"Sounds good"

"I'm going to buy dinner now or else we could be starving tonight"

"OKAYY", both of the girl said.

"WOW, the food looks good", Seori shouted.

"Hey, shhhhh. You're so noisy", Luhan shush his sister. Seori made a pouting face.

"You're cute", Yoona said. Seori smiling shyly and thanked her.

"Of course she is. Look at her brother. He is way cuter'', Luhan said arrogantly.

''Oh I feel like vomit", Yoona hold her stomach.

"Let's eat!", Seori stopped them two from fighting.
