"Can one month erase a lifetime of doubts and fears? When Y/N, scarred by a father's abandonment and a cheating ex-lover, meets Jaehyun, a man serious about winning her heart. Yet, his playful charm and unexpected sensuality leaves her questioning his intentions. Is he sincere, or is this just a game to him? Feeling an undeniable attraction towards each other they decide to give it a chance just for 30 days with the reassurance that they would go their separate ways should they not work out. As they embark on a daring month-long affair, will it be enough to heal past wounds allowing her to love again, or will it only deepen the scars and give her more reasons to never trust again? And when the final day arrives, will they walk away as if the month never happened, or will love leave its mark?"
