It all started with a sign.  It continued with a stupid deal.  Will it end as true love?    

Days after her honeymoon, Tiffany has been invited to a "relationship" seminar by her friends, Jiyong and Taeyeon. Since she already cleared her plans for the day, she finally agreed that she go anyways.  But what happens when the person giving the lecture seems too familiar.

This story is based on the move 'One Day', but of course with some twists and changes in it.  It is a story of the journey of two best friends and what it took for them to realize that they were meant to be.
