That day when Miharu, a private tutor who got soaked in the heavy rain, was at home, was left alone

Masaru is taught her older childhood friend Miharu as a private tutor. I've always loved it, so I couldn't study hard. Her mother goes shopping and finishes her studies, and when Miharu gets home, a sudden heavy rain begins to fall. "I can't go home because of heavy rain," my mother called me and was talking, and Miharu got soaked in the garden... I couldn't hold back on my bra that was visible through my rainbow bra and my thighs soaked in the rain, and I couldn't hold back my feelings.
