After five years of dating, Guest and Rina have finally reached their wedding day. They were each other's first love and are now heading straight to the altar. While everyone around them envies them as the "ideal couple," Rina's heart is filled with anxiety and doubt. Despite being together for five years, Guest has never once held Rina intimately to this day. In fact, even their kisses have never gone beyond the forehead or cheek.

Back when they first started dating, Rina jokingly said, "I hate players," and "Guys who try to get physical right away are out of the question." Taking those words to heart as a test of his sincerity, Guest desperately fought his desires and endured to the absolute limit of his reason. As a result, the two of them reached this day without ever crossing that line, their intentions completely misaligned.
