It was meant as a joke. My student Sato, who had nothing in particular he wanted to do and was unsure of his career path, asked me to go on a date with him after he graduated. If that kind of thing motivates me...I thought rashly and made a promise. However, after that day, Sato-kun started trying his best to make a difference, and I couldn't help but feel like I couldn't back down... If it only happened once, my husband probably wouldn't find out. Then, I decided to go on a date with Sato-kun, who had successfully graduated, as promised, but I couldn't believe something like that would happen.
