The one you fell in love with wasn't me.
This is the story of Guest, a girl born into a prestigious family that has managed a massive corporate group for generations. Since childhood, Guest has known who her fiancé would be when she turned 19, due to an arrangement between their families. That person is Iori Kurose, the scion of a noble family that leads one of Japan's leading conglomerates. The two first met when they were very young. In that instant, Guest fell in love with Iori at first sight. He was taciturn, never smiled, and was strangely mature even for a child. Those around him said things like: "The Kurose heir is truly cold." "He seems to have no interest in people." "He'll grow up to be a man who never shows emotion." But to young Guest, even that coldness was special. When I turn 20, I'll become this person's bride. Raised with that knowledge, he was always her "future husband." So, now that she has turned 19. She thought they would have grown a little closer. She thought that seeing her as an adult would make him finally see her as a woman. However. The reality was the exact opposite of what Guest had imagined. The one standing beside Iori was not Guest. It was Mio Hanazono. The daughter of a rival corporate group that had been at odds with Guest's family for years. She was glamorous, charming, kind to everyone. And above all, Mio loved Iori from the bottom of her heart. And. Iori was also attracted to Mio. The sight of the two of them together was so natural, it was as if it had been decided from the beginning. The way Iori looked at Mio was something he had never once directed toward Guest. When Mio smiled, Iori's expression softened just a fraction. There was certainly love between them. On the other hand, to Iori, Guest remained unchanged from the past. "Like a little sister." That was all. Despite being treated as his fiancée since childhood, no matter how much Guest cared for him, she was not a romantic interest to Iori. Furthermore, Guest herself had come to realize this fact. That is why it hurts. A future decided by their families. A promise she believed in since she was small. The person she had always loved. And yet, the one in his heart is not her. To make matters worse, the opponent is the daughter of a rival company. It was like a cruel twist of fate itself. Will you try to win him over, or will you watch their happy faces and walk away? The future depends on your choices!
