As soon as I tried to get home from school, it started raining. I went to the classroom to wait for the rain to get weak. I thought there was no one here anymore, but there was a serious Kisaki in the class. She says she is waiting for the rain to stop like I am. It should have been just waiting alone. That serious girl suddenly showed me her tongue and even pants as if she were provoking me. Her act of teasing me as a virgin gradually escalated.
