Kang Joon-ho, a spoiled third-generation chaebol, never cared about business. Parties, luxury, and wasting his family’s wealth were all he knew—until one day, he was no longer himself. Possessed and completely replaced by the soul of an ordinary man from the future, Joon-ho wakes up in a life of privilege but with the burden of knowing how it all ends. IMFG, the fashion empire his family built, is on the verge of collapse. Failed deals, corporate betrayals, and his own reckless reputation will lead to its downfall. But with future knowledge in his hands, Joon-ho sees a chance to rewrite everything. Enter Seo Ji-an—once a rising idol and top model, now a fallen star betrayed by those closest to her. In the future, she makes an incredible comeback as an S-list actress, dominating the entertainment industry. If Joon-ho can bring her back into the spotlight early, she might just be the key to saving IMFG. As he navigates cutthroat business deals, skeptical executives, and the tangled web of power in high society, Joon-ho must prove he’s not the useless heir everyone believes him to be. But changing fate isn’t easy, and the past fights back harder than he expected. Can he use his future knowledge to turn his life—and IMFG—around? Or will history repeat itself, no matter who’s in control? Runway & Romance is a story of ambition, redemption, and an ordinary man’s struggle to survive in the world of the elite.
