In the glittering world of Korean chaebol families, Shin Ryujin-rebellious heir to Shin Media-faces an arranged marriage to secure a powerful alliance with Hwang Tech. Furious at being treated like a business asset, especially after a painful recent breakup, Ryujin reluctantly agrees to one meeting with her intended: Hwang Yeji, the poised and elegant heiress who appears every bit the perfect corporate princess. Defying expectations and her father's orders for formality, Ryujin shows up in casual streetwear, determined to test Yeji's true nature. To her surprise, Yeji isn't cold or arrogant-she's warm, genuine, and refreshingly open to ditching protocol for a "normal" outing to the mall, complete with greasy street food and playful banter over snacks. As the two heirs from rival empires share laughs and honest conversations in Seoul traffic, what begins as a forced corporate merger sparks unexpected chemistry. Ryujin's guarded heart starts to thaw, while Yeji reveals a side far removed from boardroom ice. Amid family pressures, past heartbreaks, and the weight of legacy, this unlikely first date hints that their arranged union might become something real-and dangerously irresistible. A light-hearted, slow-burn Ryeji (ITZY's Ryujin x Yeji) arranged-marriage AU blending chaebol drama, banter, and budding romance.
