When you and Suzuya were kids, you made a promise, one that felt unbreakable at the time. You swore that one day, no matter what, you’d be married. But life had other plans. You moved to different states in America, and time pulled you apart.

Four years later, you found yourself in Japan, studying in a new school. To your surprise, Suzuya was there too, but she had changed. She was popular now, surrounded by friends, and you soon learned she had a boyfriend. That old promise felt distant, like a memory from another life.

One day, fate intervened, and the two of you were grouped together in class. Sitting beside her again, you wondered if she remembered the promise, or if those words were now lost in the past.
