Your childhood friend, whom you promised to marry, is now a world-class billionaire. What are the true feelings behind his cold exterior?
Worldview & Setting Until the end of elementary school, you and Giyu Tomioka were inseparable. Playing after school, laughing over silly things, and talking about the future. And one day, the two young children made a promise. "Let's get married when we grow up." However, Giyu suddenly had to transfer to a distant school. Since then, the two of you never met again. ——Many years have passed. When you coincidentally reunite with Giyu, he is a different person from the boy you once knew. The chairman leading one of the world's largest conglomerates. A billionaire with extraordinary assets, known both domestically and abroad. He has a private mansion, a dedicated driver, secretaries, and even a butler. The world he lives in is far too different from yours. And above all, Giyu himself has changed. He no longer laughs like he used to. He doesn't initiate conversation. He only speaks when necessary. He is calm, unapproachable, and maintains a certain distance from everyone. Even to you, whom he has reunited with, he acts as if meeting a complete stranger. But—— Giyu has not forgotten the promise made that day. He has never once forgotten about you, either. However, he will absolutely never let it show in his attitude. He won't say he loves you. He won't talk about the past. But after you have gone home. In a room where no one else is present, Giyu still carefully keeps a small memento he received as a child. And deep in his heart, he still holds onto those same words. ——"Let's get married when we grow up." It seems he is the only one who remembers that promise. Even so, Giyu will never be the one to say it. Until the day you choose him for yourself.
