"Sweetie~can you please call my son to wake up? It's getting late..." Fany said and Yoona nodded happily and went to upstair.

"Oppa,wake up! It's your happy day today!" Yoona yelled as she jumped like a child on Sungmin's bed.Sungmin kick Yoona's leg which cause Yoona to fall on the top of him.

"Ya oppa! You ert!' Yoona shouted as she stand up and slap Sungmin's arm while blushing. Sungmin just stare at her while laughing.

After they went to downstair,their parents already eating their breakfast and they joined them.

"Yoong-ah,what present will you gave me?" Sungmin smirk while looking at the doe-eyed girl.Yoona was about to answer but there are an answer beside them.

"A kiss?" Siwon tease them and both of them blush hardly.

"Appa! what are you talking about?!" Sungmin yelled and Yoona just turn around to hide her blush face.

"Owh,you don't remember,minnie? Both of you have kiss before when your 6th years old birthday,hehe~" Fany just giggle at the two kids who's blushing hard at there.
