Cha Seon Chaek arrives breathless and just in time - her final leap and desperate slide landing her at the selection ceremony for Prince Gyeong-seong's bride. Her heart pounds, not only from the run but from the weight of what's at stake. As gasps ripple through the room, Yi-beon quietly confesses that no matter what fate demands, there has only ever been one woman for him - Sun-chaek.

He declares that he belongs to her, now and always. In the quiet aftermath, Yi-beon takes Sun-chaek's hand and runs away with her. Between hurried breaths and lingering glances, Sun-chaek begins to realize her feelings - but hesitates, believing someone else was meant to be his destined match.

Yi-beon meets her doubts with unwavering eyes, gently clasping her hand and assuring her that the only woman in his life is her. His words leave Sun-chaek breathless and more determined than ever to enter the competition - for him, and no one else.

As the climax builds, Sun-chaek is stunned to find Eun-ae among the other participants, realizing she'll be her direct rival in the selection process. Refusing to back down, she gives her all, excelling in each challenge with quiet determination.
