Busy with yoona's arm
Their eyes met

Jessica can't help herself and lean forward yyoona did the same thing
Closing their eyes their lips crash into each other..

They share passionate kiss
Later on they break their kiss catching their breath look at each other's eyes again

"This-is-how-you-always-tease-me-yoongie..your-eyes-always-tease me..everytime you look in other's eyes make me jealous yoongie.."
Said jessica kiss yoona again without waiting for the latter's answer

Well not to mention they have long term crush into each other since they were childhood friend

Later on in the middle of the passionate kiss
Yoona's left hand slid down to jessica's
