At the end of final exams, everyone shouts for joy as they get their first taste of summer and freedom.

Tiffany Hwang takes her girlfriend, Taeyeon and her friends to a beach resort in Incheon which her family owns. 

Everyone is happy except for YulSic.

Yuri and Sica have previously dated before but Sica denies her own feelings for Yuri, breaking her heart and causing them to break up. 

Being on the beach and its romantic setting...maybe they can still fix things.
