During the entrance exam season, I was scheduled to make a home visit to one of my outstanding students, Nobuto Matsubara. He had been working hard under my guidance, aiming for university admission. However, his father strongly opposed this path, causing ongoing conflict within the family. That's why I decided to visit their home. I thought it would be just a routine home visit, but I never imagined at the time that this visit would unexpectedly deepen our relationship in ways I never expected.
