On the last day of each millennium, junior sages earn another thousand years of life when they consume celestial peaches bestowed upon their kind by the holy being Seowangmo. That’s all Cheon-rok ever really wanted – to finish her training and earn more time. But when she accidentally drops her celestial peach, that dream begins to unravel. Having fallen into the human realm, the mystical fruit tumbles through the fabric of time and space and into K-pop idol Kim Dowon’s heart, granting him a natural charisma and adoration far beyond that of any normal human. The only way to retrieve the peach without causing physical harm? Through a heartfelt kiss under the Seowangmo’s peach tree. Refusing to believe in the existence of mythical sages and stone fruit, Dowon must be convinced by Cheon-rok to cooperate before her time in this realm is up. As the two frenemies are pitted against each other, could they end up finding heaven on earth in one another’s arms?

We've only ever exchanged greetings before, but our relationship changed with a lie I blurted out in response to my ex-boyfriend's mockery. "Were you being sincere earlier? You won't save yourself anymore?" "Can one's values change in just a day or two? Men are just so ridiculous, huh? Why does that matter, anyway?!" "It matters. It's not wrong to want to do it with the girl you like." I did love my boyfriend, but I thought physical intimacy was separate from love. However... "You did like him in a romantic way, right? So why is that the case? It's instinctive, you know." The moment he approached me, my heart started pounding like crazy. "Did I make your heart flutter? If so, you're normal." We thought we would never meet again or have any involvement, but we had a miraculous reunion a year later! "Hello. I'm the new member of the planning team. I'm Ham Sooyeon." "Right. I'm your Team Leader, Cha Jihyuk." An unexpected meeting and opportunity. Could I have a more intimate connection with him this time?
