Ten years have passed since graduating from high school. At the reunion, the serious and innocent girls from their class are reunited. They are all now cute, beautiful, and accomplished career women, as if they had never been seen before! However, these girls, who were once out of reach, live sad lives, completely unrelated to romance. If only they had more fun back then... They want to recapture their youth! They want to experience passionate love! They want to let loose once in a while! They just want sex! It's no wonder that a King's Game that begins with such strange tension can become extreme!
