Homeroom teacher: A student and a student and a school trip

Hey, my favorite teacher... I've been waiting for today for three months now. My first Yamanote Line, my first Harajuku, and my last date. I loved my teacher so I was so happy that I could come alone on a school trip! Hey, Nana is the happiest girl in the world, because now the teacher has become Nana's first person. I'm glad that the teacher was the first person who touched Nana's important parts. Please, teacher, call me "Nana" until morning. Let the teacher be special.
