(Mr. Plankton X Hyunjin AU) Hyunjin has spent his entire life searching for the man whose blood runs through his veins. After a terminal diagnosis leaves him with little time to live, he sets out to find his biological father—the only piece of himself he’s never known. The only problem? He refuses to go alone. On the morning of her wedding, Y/N is dragged away by the man who broke her heart years ago. As the two embark on one final road trip across the country, old wounds reopen, long-buried feelings resurface, and the family they’ve spent their lives searching for may have been beside them all along.
