JUL-284 Rainstorm A night alone with my son's tutor Shirone Sato

I decided to ask Mr. Shirone to be a tutor for my son who is aiming to enter a national university. Shirone-san was beautiful and kind, and seemed to be able to understand her studies easily, and her son, who was full of motivation, improved his grades with excitement. Shirone was scheduled to come on this day as well, as a large typhoon was approaching. However, the Shinkansen is suspended...My son can't return from his school trip, and Shirone-san probably won't come either.
